And then right after posting, I realise the difference between these programs and other programs I run - these programs were written in assembler. I have also noticed that threaded programs don't thread properly if one of the threads calls a subroutine that is written in assembler. Sorry about the noise - but if anyone can explain to me why this happens I would appreciate it. -- Stephen Montgomery-Smith stephen@math.missouri.edu http://www.math.missouri.edu/~stephen To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
