FreeBSD thread issues

[Charles Sprickman]

Please excuse the top-post...

I will make an offer again, anyone that needs access to a FreeBSD box for 
development, please contact me.  I have a 5.4 box that I can create a jail 
on (ie: you can have a sandboxed root) and a 4.11 box as well.

Thanks,

Charles
