I would finger the scheduler, at least partially. There's no magic in
this world and my Erlang version does not fare much better. Erlang
too uses a GC and when a lot of threads load all that data into
memory things are bound to get nasty.
The results for Erlang are more uniform, though. All the delays are
all within 3-4s if I have 3s as the cut-off time and with GHC the
delays are all over the place.
