I am very curious if using this library on your system will help 
increase the load you are able to put on the dual core system.

People that are running Asterisk on Solaris have noted that using the 
mtmalloc library allows for much higher call density.  I am hoping that 
hoard will let the people running Asterisk on Linux see similar 
performance improvements, but I have yet to convince anyone to give it a 
try and let me know how it goes.  :)
