Lots of the functionality that seems harmless in the python scripts you write may actally do bad things within the python source itself.

Yes, definitely. It's not particularly hard but you do need to be happy making changes to GCC, Binutils and uClibc/Glibc. Well, yes, but fork is typically invoked from a script interpreter if you actually call fork() or system() or `backquotes` from your script. You could just not do that. I believe even Python has rudimentary thread support :-) I would have thought system and backquotes worked fine. If they use the libc calls system() and popen() you may be right. -- Jamie ___ uClinux-dev mailing list uClinux-dev@uclinux.org http://mailman.uclinux.org/mailman/listinfo/uclinux-dev This message was resent by uclinux-dev@uclinux.org To unsubscribe see: http://mailman.uclinux.org/mailman/options/uclinux-dev
