Hmm ... so if we were talking about Unix, a reasonable solution would
be to avoid having a separate shell process, either by telling the shell
to "exec" the postmaster or by using fork/exec directly with no shell.
A 99% solution would be to use "&" so that the shell doesn't wait around
for the postmaster to die.

Are any of those ideas tenable on Windows?
