This "threat" of some program someday eventualy dynamic loading a module
that expects to be able to start threads when the program that loaded it
wasn't already expecting to need a fully thread-safe environment really
must be stomped out.

I for one am extremely opposed to forcing everything into paying the
cost of running in a fully thread-safe environment just on the off
chance that somehow some thread-needy module might be loaded by some
other associated application.  Those who want the freedom to plug&play
with anything any time might be willing to pay price, but for those of
us who have well defined requirements which allow us to know in advance
when and where we'll use various components there's no need.
