Matt,

I was considering moving the MOH files to a RAM disk at boot and then 
playing them from there to handle that problem.  I'm not sure it's 
necessary, though.  Currently, QueueMetrics is showing 100 callers in 
queue, but iostat is showing almost no read activity on the disk.  My 
guess is that Linux is already caching the files to memory.  Of course, 
this is entirely dependent on the amout of memory in the system.
