[erlang-questions] on_load

[Zoltan Lajos Kis]

http://www.erlang.org/doc/reference_manual/code_loading.html

"A process that calls any function in a module whose on_load function has
not yet returned will be suspended until the on_load function has
returned."

Isn't there a deadlock with start() waiting for auto_start() to finish and
vice versa?

Regards,
Zoltan.
