This patch simplified Win32 signaling code per discussion in hackers. In
this implementation, each process will have a named (by its pid) mutex,
named shared memory area and named event in global namespace. The process

Nope, we need to pass the handle. Only one process can be the
server-side of the pipe, and once the postmaster has o
Revised patch to avoid "lost signals before signaling mechanism is set up
in Win32". This was tested by plus a line:
Sleep(10*1000);
in the front of pgwin32_signal_initialize().
