  Um, hasn't someone already done a lot/all of this work?  I know
Klaus did a lot of libc-hacking, and over a year ago at that. 
Take a peek at /usr/src/lib/libc/include/reentrant.h, and, for
example, /usr/src/lib/libc/stdlib/random.c (grep for REENT or
mutex).

  The reentrant.h describes some of the rationale for why things
are done the way they are (you can compile with your own mutex
ops, for example).
