Maybe I didn't ever say it loudly or strongly enough. There is a
*critical* flaw in the OS X versions before 2.1. This is caused by a bug
in an OS X system call that we were making - it returns memory to the
app that cannot be passed to free(2), but we did so anyway (because its
supposed to possible).

This can lead to major memory corruption and was the source of at least
many crashes close in time to when file import/embed was taking place.

Nobody should be using 2.0.5 or earlier on OS X without a very, very
good reason.
