Takashi Yano f78009cb1c Cygwin: pipe: Fix a regression that raw_write() slows down
After the commit 7f3c225325, writing to pipe extremely slows down.
This is because cygwait(select_sem, 10, cw_cancel) is called even
when write operation is already completed. With this patch, the
cygwait() is called only if the write operation is not completed.
