We have never had any need for pipes with the default 64K
capacity on Linux. Our pipes are only used for tiny writes
in signal handlers and to perform parent shutdown detection.
With the current /proc/sys/fs/pipe-user-pages-soft
default, only 1024 pipes can be created by an unprivileged
user before Linux clamps down the pipe size to 4K (a single page)
for newly-created pipes[1].
So avoid penalizing OTHER pipe users who could benefit from the
increased capacity and use only a single page for ourselves.

Some versions of test-unit will fail if an unspecified test is
attempted via "-n", so we need to define an empty test.
We cannot use "skip", either, as that seems exclusive to
minitest; and we won't use minitest since it has more
incompatible changes than test-unit over the last 8 years.
The memory leak test is gone since we're more versed in the
Ruby C API nowadays, modern GCs + mallocs may be less
predictable about releasing memory back to the OS.

This fixes a bug introduced in
commit fe83ead4eae6f011fa15f506cd80cb4256813a92
(GNUmakefile: fix clean gem build + reduce build cruft)
which broke clean Ruby installations without an existing
unicorn gem installed :x

As of r40610 in ruby trunk, internal encoding is ignored if
external coding is ASCII-8BIT (binary)

It's better to show errors and backtraces when stuff
breaks

IO#reopen in Rubinius seems to munge the O_APPEND flag when passed a
path, however passing an actual IO object. However, at the system call
level, everything is the same.

Avoid Tempfile.new(nil), which breaks under Ruby 1.9.2
and was probably a bad idea to begin with.

This ensures any string literals that pop up in *our* code will
just be a bag of bytes. This shouldn't affect/fix/break
existing apps in most cases, but most constants will always have
the "correct" encoding (none!) to be consistent with HTTP/socket
expectations. Since this comment affects things only on a
per-source basis, it won't affect existing apps with the
exception of strings we pass to the Rack application.
This will eventually allow us to get rid of that Unicorn::Z
constant, too.

Otherwise they might be picked up by the GC during the
other tests (exposed by Ruby 1.9.1-p243).

test/test_helper doesn't seem to be required correctly anymore,
since we know our own module/test names don't conflict, just
fix RUBYLIB to include $(test_prefix)
With test_util.rb, using #reopen with Tempfile objects seems
prone to the objects being closed. Not completely sure what is
going on but I'll just sidestep around it since I've stopped
trusting Tempfile by now...

Ensure we preserve both internal and external encodings
when reopening logs.
