| H A D | sys_pipe.c | diff 118230 Wed Jul 30 20:50:37 MDT 2003 pb 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.
