You still didn't answer most of these questions, or what kernel you're 
using.  I ask about the full rebuild of OpenLDAP because the changes in the 
connection code changed the size of the connection struct, and I know it 
will fail without that rebuild.

A backtrace of the hang would be useful for diagnosis, since so far neither 
Howard nor I can reproduce this.

I'd also like to know the Linux kernel version, since some of the changes 
affect epoll (linux 2.6) specifically.  I'm running a 2.6.18 kernel+patches 
currently.

Also, what flags are you passing to gcc while building?  -g? -O2? etc. 
I.e., are you putting optimizations into place.

Thanks,
Quanah
