This is wrong! Pressing cancel will simply drop the connection to the
plug-in, which will happily run (since it has no way of detecting this)
for as long as it wants. Only on the next call the a libgimp function
causing communication will libgimp call exit(0).
_No_ files or other persistent resources will ever be removed without
special support from the plug-in (which I do not see in the plug-ins), and
there is no way of detecting this from a plug-in while it runs.

Ok. However, the effect of Cancel is about the same as a delayed kill, and
I regard this as serious enough as to warn about :(
I admit that an error message might not be appropriate, but the current
canceling mechanism is unstable at least.

I mailed it to the list quite a few times.
