I read your paper and it describes the very same technique I was planning
to implement, but the trick with sigaltstack() seems very ugly to me. That's
why I poked around Solaris' man pages and found ucontext(3) functions. Anyway
since you already have done all the work, it's pointless for me to reinvent the 
wheel. Besides this, GNU Pth is certainly more tested than my solution would
ever be. Well, next time I should check for GNU stuff before I plan doing something.

I will definitely use it. Thank you for this great software... !
