Hello Heikki,
Now that I've finished the detour and committed and backpatched the changes
to the way latency is calculated, we can get back to this patch. It needs to
be rebased.
Before rebasing, I think that there are a few small problems with the
modification applied to switch from an integer range to double.
(1) ISTM that the + 0.5 which remains in the PoissonRand computation comes
from the previous integer approach and is not needed here. If I'm not
mistaken the formula should be plain:
-log(uniform) * center
(2) I'm not sure of the name "center", I think that "lambda" or
"mean" would be more appropriate.
(3) I wish that the maximum implied multiplier could be explicitely
documented in the source code. From pg_rand48 source code, I think
that it is 33.27106466687737
