Courtesy of Planet Python , I stumbledover Peter Bengtsson's puzzlement with Python's tempfile module ,especially the mkstemp() function. It's an understandablepuzzlement, because what's going on is fairly tied to Unix semantics(although Python supports mkstemp() on all platforms).

On Solaris 9, my $PATH is

A one-line addition to httpd.conf : 30 seconds.
Restarting Apache: 30 seconds.
Making sure that the addition was the right thing to do to an oldversion of Apache and wouldn't kill the server: much longer .

Accidentally using kill -USR2 instead of kill -USR1 to gracefullyrestart the
