I assume you're talking about USE_ITHREADS.  Can you elaborate on exactly
what bustage you're talking about?

AFAIK, the only way the USE_ITHREADS code is currently busted is for
regular expressions that modify the optree directly (which is supposed
to be readonly).  I don't know of any others.

Note that that problem is irrelevant unless perl_clone() is used to
create an interpreter.  If you're running independent interpreters,
USE_ITHREADS is in fact completely safe, AFAIK.
