Comment(by int-e):

 (further comments on my patches above)

 Personally I think the bugfix is a no-brainer; the hard part was really
 figuring out why just masking exceptions interruptably was not enough. It
 still needs a test case, but I can try writing one tonight.

 For the faster timeout, I've asked Bas for a copy of the benchmarks he
 developed two years ago in connection with #4963. But I expect it to be a
 clear win, time-wise.
