[Mailman] [srmtester]user case tests

 Flavia,

 I saw the pin03 is recently failing for LBL, can you tell us why?

 space02 is still failing for us due to the fact we do not support putting 
permanent files in volatile spaces.

and I wish you read my comments about "checkGarbageCollector". Basically we 
do not provide request token if srm*()  fails the initial screening, and 
this is consistent of the spec. So clients cann't assume a request token for 
each of the asynchornized functions.
