Modified files:
sys/kern sys_pipe.c
Log:
Remove test in pipe_write() which causes write(2) to return EAGAIN
on a non-blocking pipe in cases where select(2) returns the file
descriptor as ready for write. This in turns causes libc_r, for
one, to busy wait in such cases.
Note: it is a quick performance fix, a more complex fix might be
required in case this turns out to have unexpected side effects.
