Its had zero attention because the rtai patch is a cast iron bitch to mold 
to a given kernel version.  So there are several burps in the barrel by 
now.  The strange thing is that when the sleeps happen, its as if the 
software interrupt it needs to send a message as a for instant, gets lost.  
The rest of the system is fine except kmail is frozen in its tracks, while 
gkrellm is showing  all 4 cores running at 2 or 3%, the machine isn't busy 
at all.

Not the same kernel Ric. the 10.04.4 install uses a highly modified 2.6.32 
kernel wit the rtai patch kit.  The target for the 12.04.2 installs is the 
xenomai kit on a 3.5.7 kernel.  And while the realtime performance of the 
2.6.32+rtai kernel is great, that patch has not kept pace with kernel 
changes, and the xenomai kit was easier to get working.  But we are leading 
up to a stable 2.6 release of Linuxcnc, and the kernel in the released 
version will likely be even newer than 3.5.7.

As for the mail, my corpus is over a decade old, much of it converted to 
maildir formats since kmail falls over face first in its morning oatmeal 
when an individual mailfile exceed 2Gb.  Setting up a big folder list in T-
Bird is less than intuitive.  But the real 128 thousand dollar question is 
how to migrate this email corpus to T-Bird, and setup a matching set of 
sort filters.  I haven't a clue.

Cheers, Gene
