Modified Files:
        src/sys/kern: sys_pipe.c

Log Message:
pipe(2): Don't cv_wait_sig in a loop without breaking on signal.

If a signal does arrive, it will turn into a busy wait!  Not helpful.

But this wait should be limited to scheduling delays for other
threads anyway, not for general I/O, so there's no need to be
interruptible by a signal.

Prompted by:
