Sounds like a great improvement.

As mentioned on IRC, prior to the recent printer_list tdb changes the
printcap cache was stored in memory. Updates in the main smbd process
ensured new client connections saw up-to-date printer lists. Anyhow
I agree, with printer_list tdb changes in 3.6 this belongs in the
background queue process.

I don't have a problem with this. That said, I only use interactive mode
for gdb and valgrind sessions.
