Hi,

I have just a few general remarks:
- - pre16 is a very old version
- - Thomas's socket api library also makes heavy use of multithreading,
apparently without many problems. Maybe you can have a look into
that.
- - sctplib was never written to be tread-safe, and I do not know what
it would take to make it that way.
- - we can only release bug-fixes for the current versions

Regards,
Andreas
