[PATCH] D23107: [MSAN][MIPS] Fix fork.cc test on MIPS

Well, that's simply another way of saying "hangs while reading the chained origins".  Reducing the number of child processes is likely to reduce the probability of the deadlock instead of eliminating it. Anyway, this sounds like a bug in the msan runtime library.

This test is for the ChainedOriginDepotLockAll() logic in msan_interceptors.cc. Could you verify that the fork interceptor is being used on MIPS? I wonder if we need to intercept something else, like vfork.
