Ok, that fortunate. If it was important, I would have to see if it would change its relative priority and possibly reschedule my todo list. Arun@ has done a lot on that front, but it needs more work to be usable. The more complex the userland problems the more we need a debugger. > I have corresponded briefly with jdp, and from what he tells me there's > something really wrong with signal handling in the kernel.

I welcome any attempt; > however unrelated to libthr, to clean up signal handling there. I'll keep it in mind. I probably don't have the time to look for anything weird, but I might just happen to run into something... -- Marcel Moolenaar USPA: A-39004 marcel@xcllnt.net
