For the time being, is it possible to use
serialization in multi-thread applications using
mutexes around serialization methods, or should it
totally be avoided?
Thanks,
Andrej

It has been determined that the boost serialization - contrary to intention - is not currently thread safe. This will be addressed in a future release.

Using a core dump and gdb, here is a backtrace. It appears it crashed inside the multi-thread library. Any advice is appreciated..
