I already tried the above in one of my many failed attempts to fix this
in cygrunsrv.  AFAICT, this won't work because the daemon will (re)set
signal handling to meet its needs.  In the case of PostgreSQL's
postmaster, the following occurs:

    1. cygrunsrv sets SIGTERM to SIG_IGN
    2. postmaster inherits that SIGTERM is ignored
    3. postmaster sets its SIGTERM (and other signal) handling during
       initialization
    4. postmaster responds to the first signal sent during system
       shutdown
    5. postmaster takes too long to shut down possibly corrupting the
       database

Any other ideas?

Thanks,
Jason
