[erlang-questions] Increase the handle limit

I don't think you can.

I bump against this all the time on the Mac. 

Erlang uses the FD_SETSIZE setting from the system header files when compiled, normally 1024.

Editing this value and re-compiling Erlang causes epmd to stop working. 

My solution is to save the old epmd and recompile after editing the system header files.
