In the wrong order is certainly a possibility also, though I was more
concerned about the hang. When the actions overlap, I think anything can
happen.

I would think that any application that uses the clipboard would be
vulnerable to this. For example, I think I can trigger the issue
with
two Ctrl-V's in succession with the edittest example in lazarus.
Start
it and say libre office (I used a spreadsheet with about 1000
lines of
data.) Select and copy a large block in the spreadsheet, and
then hold
down the Ctrl+v key in edittest. A few copies will appear very
quickly,
but then the application hangs for several seconds (at least).
Lazarus
itself can be made to hang in the same way.
Do you mean the copies could be processed in the wrong order?
Mattias
I have done some more investigation of this, and come up with a possible
patch
