checking Terminated doesn't work. If that's how the these
ExecuteInThread class methods on TThread are going work then they should be
removed because they don't have significant function and likely would
Eg. of confusion when trying to use ExecuteInThread Q: How does OnStatus
work? A: It doesn't. Q: How can I check if my thread method is terminated?
A: Forget about Thread.Terminated, you'll need to set a flag somewhere or
create you own solution. Q: How can I suspend my method and safely join the
main thread, because I normally use Synchronize? A: You'll have to do
without Synchronize or maybe figure out a workaround.
So IMO ExecuteInThread should either be removed or these problems should be
