Assume it’s multiprocessor-safe

As Matthew Dillon notes in a recent post, procedures are now assumed to be MPSAFE (i.e. without the Giant Lock) by default.  Any new work should follow this idea, and it doesn’t have to be documented specially.  The inverse used to be true, where the code that happened to work without the Lock was rare, and therefore needed to be pointed out.   Now, the good result is the norm.
