"On a 64-bit system, consuming 8M of address space is a drop in the ocean."

Let me disagree here. Python always allocates faulthandler stack, even if faulthandler is not used. Even when faulthandler is used, I would prefer to not waste memory if 8 KiB is good enough.

By the way, I just created bpo-37851 to allocate this stack at the first faulthandler usage, instead of always allocating it, even when faulthandler is not used.

I wrote PR 15276 to use a stack of SIGSTKSZ*2 bytes. According to 
msg349694, it does fix the crash.

Can someone please double check that PR 15276 fix test_faulthandler on a platform where the test crash without this change?
