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.
