increase default thread stack size to 80k
I've been looking for data that would suggest a good default, and since little has shown up, i'm doing this based on the limited data I have. the value 80k is chosen to accommodate 64k of application data (which happens to be the size of the buffer in git that made it crash without a patch to call pthread_attr_setstacksize) plus the max stack usage of most libc functions (with a few exceptions like crypt, which will be fixed soon to avoid excessive stack usage, and [n]ftw, which inherently uses a fair bit in recursive directory searching). if further evidence emerges suggesting that the default should be larger, I'll consider changing it again, but I'd like to avoid it getting too large to avoid the issues of large commit charge and rapid address space exhaustion on 32-bit machines.
