I've found that privoxy is a good program to test threads. It does

libthr: tends to segfault (sig11). Occasional DNS resolution issues.
libkse: tends to segfault (sig11), I've gotten my box to crash
once too (BAD!). ^C still doesn't kill the process.
Occasional DNS resolution issues. Here's the output from the
console:

When it worked, it worked better under thr and kse.
