Even if the download does in fact stop during the decode and save, I don't 
think that's the cause of what I'm seeing.  When I download large rar 
files using one server thread, the 0.14.2 version will generally download 
as 800 to 900 KB/Sec, and the CVS version is consistently 1/4 that speed 
or slower.
