One of the things is that a default VOP for this means that the

om scratch.
It seems that freebsd has implemented some of the functions in
wchar.h, but not many or none of the ones in wctype.h.
NetBSD seems to have these integrated, you can crib from them
as I am trying to do with my miniscule free time.

No way to work around this? Shouldn't the thread exit library
know which stack exactly to clean up even in the context of a
signal handler?

cfl = curthread->cancelflags;
+ cfl &= (PTHREAD_CANCEL_ASYNCHRONOUS|PTHREAD_AT_CANCEL_POINT);
+ if (cfl != 0)
pthread_testcancel();

FreeBSD
at home seems to cause stalls, I'll try my netbsd laptop at home
and see if i can reproduce the problem. I thought it was my crappy
