ping [PATCH] Fix a deadlock bug in static variable initialization in libsupc++

[Jason Merrill]

Thanks for fixing this, and sorry about the delay.

It seems like the skip list code is only used to support throwing the 
recursive_init_exception.  I think I'd prefer to just drop that and let 
recursive initialization deadlock (which is allowed under undefined 
behavior) rather than add that overhead to the common case.
