[PATCH] tryopen: avoid ambiguous name for subst function

[Eric Wong <normalperson@yhbt.net>]

Define rb_thread_blocking_region as a macro for MRI 1.8
to prevent confusing output in tools such as valgrind/gdb.

 I've pushed this to kgio master along with two of funny-falcon's
 patches:

 Sokolov Yura 'funny-falcon (2):
        Fix UnixClientReadServerWrite test class name
        use rb_str_subseq for tail string on write
