If it handles the restart-after-backend-crash scenario and correctly
locks out starting a fresh postmaster (after postmaster crash) until
all old backends are gone, then it's probably ready to commit for
more-widespread testing.
I note that sysv_shmem contains some #ifdef WIN32 and #ifdef __CYGWIN__
kluges; will it now be possible to remove those, or will the Cygwin
build still be using that code?
