[erlang-bugs] lists:delete on tmp supervisors

[Siri Hansen]

Hello Evgeniy!

Thank you for this contribution. The list representation was introduced by a
correction that was done in R14B02, where it was decided not to save the
initial arguments for dynamic temporary processes. Thus the original dict
was no longer needed for this type of processes, and a list was used
instead. I think your patch is a good improvement. I will try to fit it into
the coming release.

Regards
