On windows I know there is a call to flush all virtual memory out. Is

The ONLY way that could happen is if the boolean happens to be set in
a worker thread's method that still has mor
Right. But in the case of an array of booleans that will be polled
and an exit condition will only be met if all booleans are set to
true. The order in which a polling thread sees them as being true has
no bearing on the functionality.

I'm needing help to take my Lazarus app, elevate process to root
(using GUI prompt like GKSU) and I want to drop back down to the

Ubuntu has port restrictions for low port numbers. I'm developing a
platform that happens to use ports for HTTP, XMPP, e

There are a million ways to accomplish safe thread usage without waitfor...

This seems like a discussion of semantics more than anything. In an
application thread if you say WAITFOR something then the app cannot
process messages b/c the execution is put on hold until WAITFOR
returns. This is normal behaviour, IMO.
So if this is just an exercise, I really don't see a pro
