 Hi Kristan,

 having a quick look at the current code, it looks like the session
 workshop overflow issue ''should'' be solved - but I would want to write a
 regression test to check that restarting sessions does not change
 {{{sp->ws->f}}}. Trouble is that currently the git head seems to have some
 serious issues with the VSL (similar to but not the same as #1065) and
 (damn it) I don't have enough time atm to fix these first.

 On the question of when to restart, having a quick look at the many calls
 to HSH_Deref in the current code, it is pretty clear that the waitinglist
 is simply rushed for too many cases. As this bug has not received any
 attention for long, I have not yet spent any brain-cycles on the current
 code, but I don't see the concerns I have raised in comment #comment:2

 Thanks, Nils
