Or as easy as in any other platform - and as easy to screw up. Personally I prefer to use multiprocessing [which is a module that 'simulates' threads using separate processes]. IMO, it is hard to screw up as you don't get any shared-state for free. > This has probably been brought up already, so if it has, thanks anyway -- Adam Tauno Williams <awilliam(a)whitemice.org> LPIC-1, Novell CLA <http://www.whitemiceconsulting.com> OpenGroupware, Cyrus IMAPd, Postfix, OpenLDAP, Samba

Take a look at the threading and multiprocessing modules. Geremy Condra
