Thanks for the tip Scott. Considering that the megaco testing rig I'm 
building will need to open that many calls, it's a good thing to know. 
I'll do some comparisons when the scope of test reaches that magnitude.

A quick grep reveals that ets defaults are used in 
otp_src_R9B-1/lib/megaco/src/engine/*.erl Maybe a bit more profiling and 
statistics collecting could improve an already stunning protocol stack? (-:
