Since I'm here at LLNL and we happen to have a few of the large systems maybe 
I should chime in.  While it is true our large systems (many thousands of 
nodes) use a timeout value of 300s, it is not true that they prevent all of 
our timeouts.  The 300s value has just shown itself through actual usage to 
prevent 99% of our timeouts and still allow reasonable length recovery times.  
It certainly does not prevent all of our timeouts.  To get to that point I 
feel the only viable solution is to validate the new adaptive timeout feature 
for our production use.
