I guess a long time ago, threading support in operating systems wasn't very widespread, but these days all our supported platforms have it. Is it still useful for production purposes to configure --without-threads? Do people use this option for something else than curiosity of mind?
_decimal is about 12% faster without threads, because the expensive thread local context can be disabled.
On OpenBSD threading leads to strange problems like delayed signals in the REPL http://bugs.python.org/issue8714 . Without threads these problems don't occur.
