Modified Files:
src/sys/kern: sys_pipe.c
Log Message:
Fix a deadlock where one thread writes to a pipe, has more data
and no space in the pipe and waits on "pipe_wcv" while the reader
is closing the pipe and waits on "pipe_draincv".
Swap the test for "PIPE_EOF" and the "cv_wait_sig()" in "pipe_write()".
