-1 on the implementation here, because it didn't start with current CVS, so
is missing important work that went into improving this module on Windows
for 2.3.  Whether spawned/forked processes inherit descriptors for "temp
files" is also a security issue that's addressed in current CVS but seemed
to have gotten dropped on the floor here.

A note on UI:  for many programmers, "it's a feature" that temp file names
contain the pid.  I don't think we can get away with taking that away no
matter how stridently someone claims it's bad for us <wink>.
