See https://mail.scipy.org/pipermail/numpy-discussion/2012-August/063589.html and replies in that thread.

Quote from an Apple engineer in that thread:

"For API outside of POSIX, including GCD and technologies like Accelerate, we do not support usage on both sides of a fork(). For this reason among others, use of fork() without exec is discouraged in general in processes that use layers above POSIX."

That's probably because I know nothing about the issue, is there any reference I can read about?

But in general, please feel free populate new items in the wiki page.

I've been wishing we'd stop shipping Accelerate for years, because of
how it breaks multiprocessing – that doesn't seem to be on your list
yet.
