That'd be nice, to see what each is apparently getting up to.
Speaking of threads, there's more low level things that need to be
reviewed for safety.
- gethostbyname and friends definitely
- string->symbol I think needs protection
- symbol->keyword might be ok, but the SCM_DEFER_INTS
could become some explicit mutex
I was doing some of the C bits with mutexes, but I'm thinking it may
be better just to demand the "_r" functions whenever threading is
enabled. If the posix threading funcs exist then so should the _r's,
and those _r's will give maximum concurrency.
