Cygwin: signal: Fix a short period of deadlock ...
The main thread waits for the sig thread to read the signal pipe by
calling Sleep(10) if writing to the signal pipe has failed. However,
if the signal thread waiting for another signal being handled in the
main thread, the sig thread does not read the signal pipe. To avoid
such a situation, this patch replaces Sleep(10) to cygwait().
