I'm running the test suite now .. it hangs in testsignal for some reason. testthread seems to hang too, which may be related. (but testthreading completes?) If I make another change, to call PyOSInitInterrupts just after PyInitialize in Modules/main.c, these two tests pass. PyInitialize believes it's already initialized so returns without doing anything. But unexec doesn't preserve signal handlers, so this must be re-done explicitly.

Y'know, I wrote that as a joke, and it's quite FAST that you've taken t and made it real. Very cool too, congrats!

Since it looks like you implemented the meat of it as a module, I wonder if it couldn't be cleaned up (with the interrupt reset either pulled in the extension or exposed to Python) and added to Python 2.3?
