Yes.

No. This issue was raised by Ole, and I fixed it, as I told, but not
committed (not tested enough; also the 2.0 one was buggy; I also (like Ole
for his DTM - if I'm right) get some rare exception under heavy load tests,
and need to track it down).
BTW the scheme is the same as before: wait and notify (not notifyAll), in
the same places, plus many fixes.

OK, I'll try to find the time for that also. You'd like something for JBG
docs (for sell) ?

Ugh ? Torquemada ? Would you like to burn me at the stake like he did ?
Beware then, I will fortify my email server, and you won't ever pass. Ah !
LOL!
