It happens every time you load and unload, surely?
No. An initialiser is only ever run once per run of the RTS.
Oh, I see. Yes, sorry.
Since it's of the order of the number of uniquely identified
initialisers, it's arguably not a memory leak so much as a static
overhead. The only way to get a continuous leak is to load and unload an
endless stream of _different_ modules, each with their own initialisers.
I would call it a leak if something that is no longer being used cannot be
reclaimed. The endless stream of different modules is possible in
long-running systems where the code being run evolves or changes over time
(e.g. something like lambdabot, which runs user-provided code).
