That is possible. I could make them a compile-time option (I think a
run-time option might hurt performance), and investigating that is on
my to-do list. My fear with making such assertions optional, though,
is that nobody but me would ever use them.

One of the reasons I made this change was to try to nail down whether
some of the things that have broken with native pthreads are tripping
over pthreads bugs or just having their own bugs exposed; this makes
the latter much more obvious when it happens.
