00da8664cd Mach_thread_self() can in theory "return mach_port_null if a resource shortage prevented the reception of the send right" so add a check in each case. (there's nothing we can do about it but at least we can notice.)

2ccdd80953 Extend forktest so that it does allocation before the fork and collection afterwards; this ensures that we hit the read barrier and thus exercise the exception handling. 
After forking in the child, re-create exception port and exception thread, and re-register the (only) thread with that port.

57e2dbccf3 Make mps manual sphinx extensions compatible with recent versions of sphinx: 
1. Don't use the html_use_smartypants directive (smartquotes are on by default now).
2. Don't call make_admonition but inherit from BaseAdmonition instead.
3. Set the title of an admonition via the visit method instead of hacking the title node (which is now non-existent as a result of item 2).
