HTTP connections remain persistent after a failed Content-MD5, this
prevents the MogileFS monitor from generating excessive TIME-WAIT
connections.

Linux only: Idle HTTP connections are automatically closed under FD
pressure from systems with too many trackers.  This adds zero
overhead unless the process runs out of file descriptors.

"server aio_threads = <digit>" is supported and attempts to mimic the
Perlbal interface.  There is no error reporting nor reporting of the
current thread count.  Requests are silently capped in the 1-100
(inclusive) range.

The "shutdown" command from Perlbal is also supported.

The Content-Range response header (for partial requests) was missing a
'\r' and thus not compliant with extremely strict HTTP parsers.
