Our usage of File::Temp _will_ cleanup the files on destruction, the
problem is an unhandled ALRM will cause the program to terminate
without doing those cleanups.
qpsmtpd-forkserver DOES have an ALRM handler, and it works well:
$SIG{ALRM} = sub {
print $client "421 Connection Timed Out\n";
::log(LOGINFO, "Connection Timed Out");
exit; };
The important part of that handler is the C< exit > call. It allows
normal perl termination and thus cleanup.
I'll bet if you put $SIG{ALRM} = sub { exit; }; in qpsmtpd (which
pperl uses) then 99% of your issues will go away.
