IIRC - all setjmp and other usually-thread-agnostic calls in a normal clib were redesigned to use TLS in the Win32 msvcrt lib, long before most Unixes considered implementing threads :) I believe on win32 you will be fine, I'd be more worried about the thread implementations. This sure sounds like an abstraction we should assist with using apr. Bill
