Let's keep this reasonably close. FreeBSD does not yet have kernel threads, period. The rest of your comment is right, I think, in spirit, but don't toss the thread word around like that, not when you're already using it to refer to pthreads, which aren't kernel threads. Any thread running today on FreeBSD is (must be) running in the context of a single process at a time. Of course, that point about threads could change, tomorrow, but it's right as of this moment. > > Dave. > _________________________ > David Green-Seed > davidg@autodebit.com > Automated Debit Systems > > >-----Original Message----- > >From: spork [SMTP:spork@super-g.com] > >Sent: Monday, October 20, 1997 5:42 PM > >To: dyson@FreeBSD.ORG > >Cc: Greg Lehey; current@FreeBSD.ORG > >Subject: Re: usable current SNAP > > > >Hello, > > > >Since everyone's on the topic, how about this application: > > > >I need to build a big database server, and am looking to run it on a > >dual-processor machine.
