es, it was used in smbd/process.c - but just because there was no other level
of caching available. The caching of rintcap per client was broken by design,
see bug 6448 for that. This is exactly the place where lp_printcap_cache_time
should be placed, it should be obsolete in smbd/process.c then. Without using
printcap cahe time at this place a large print server will pull all printers
every second which isn't fun if you have a cups server with hundreds of
printer. ;-)

okay, I'll split it it up and just check in the monotonic time part now and do
some more testing with the printcap caching and the changes that should also be
made in smbd/process.c later on.
