I'm wondering: There are other, less obvious cases of suicide that
currently lead to a crash. I encountered this when trying to close the
Gem-window by watching for the <Esc> key with [gemkeyname] connected
to [0, destroy(--[gemwin]. This also crashes Pd and according to
IOhannes for a similar reason. Inserting a [delay] in between this
will fix it as well. However here not a single object is deleted.
Which object should be "marked" here?

Ciao
