make that call in the main thread?
There are two possible solutions. The easiest solution here is simply
to use nsITimer. It will fire a periodic notification on the main thread.
The more complicated solution that I don't recommend unless it's
absolutely
necessary is to create a separate thread and periodically send the main
thread an event (a nsIRunnable) when you want it to do something. See
nsIThreadManager/nsIThread for details. The problem with this approach is
that you have to be very careful about thread synchronization if there
are
any shared structures.
Does Mozilla assumes that has the control of the main thread?
(And wants to run a message loop on it?)
