[fpc-pascal] TThread.Suspend

[Mark Morgan Lloyd]

First question: is Start an accurate replacement for Resume, or can it 
only be used to start a thread created in the suspended state?

Second question: now that Suspend is deprecated, what should a thread do 
if it wants to stop processing pending a subsequent resume? Please note 
that I'm asking about a thread suspending itself: I'm aware of the 
issues that argue against external suspension (on platforms where this 
is possible).

I note that http://www.freepascal.org/docs-html/rtl/classes/tthread.html 
gives no indication that Suspend and Resume are deprecated.

The usage case is a system emulating multiple processors. If any 
processor other than the first recognises certain conditions it is to 
stop running, pending notification from the first processor that (e.g.) 
an interrupt has been handled.
