I can confirm that the process with the applied patch runs far better than without - on a 
7.0-PRERELEASE FreeBSD 7.0-PRERELEASE (i386). It's a P4 System with HT enabled (Kernel is compiled 
with SMP).

Without the patch, the system is continuously accessing the Harddisk. The Datarate is about 6MB/s - 
i don't know what's going on there. There's enough RAM marked as free (about 460MB), though no 
reason for swapping.
I don't see this behaviour if the Code is linked against -pthread.
If i apply the patch to libkse, then the process linked against -lkse behaves like one against -pthread.
Without the patch, i've also the fatal error messages as stated by Mark Kirkwood, with the patch 
they are gone.

Looks good to me!
