Just to clarify, the value is _based_ on (2 * PacketLifeTime + local CA ack 
delay).  For example, if local CA ack delay is 0, then local ack timeout = 
PacketLifeTime + 1.

The work-arounds were only suggestions to use until a fix is in place and to 
verify that this really is the problem.  I do plan on submitting a fix.
