BUT, that cannot be used to prioritize a thread. While you block a thread

No, basically a sleeping thread is marked in the scheduler as "do not schedule
for nn
ticks". The thread doesn't run to evaluate if it should contiue. That is the
scheduler/kernel's task.
Looking at the TThread documentation, since Suspend and Resume are
deprecated should Suspended be similarly annotated?
Looking at
http://wiki.lazarus.freepascal.org/Multithreaded_Application_Tutorial#Initialization_and_Finalization
there are dire warnings that TThread.Create() shouldn't be overridden.
Should this be in the documentation if it's a significant issue?
Sorry about the niggles, I'm currently trying to track down a race
condition.
