MultiTasking: Needs "id_running?" function

Hello,


I find that there is no function in the MT preview release to call to
find out if a particular task is running or not.  This is rather important
to have in some apps that will allow user input to determine which
threads will be run.  Some tasks will not be allowed to start if yet
some other tasks are running.

For example, the user clicks "Save" which starts the file save task for
that app, then clicks "Exit" while the file save is still in progress.
Obviously you want to stop the program from aborting and display a 
message telling the user to wait for the file save to complete.

  if task_running(Task_ID1) then
    MessageBoxOk("Your data is being saved...please wait...")
  end if

There's also the possibility (optional) of detecting if *any* tasks are still
running (other than task=0) with something like this:

  if task_any_running() then
    --(code here)
  end if


Yes, i could manage keeping track of running (or not) tasks myself,
but then i'd have to re-wrap some of the task function calls :)


Take care,
Al

And, good luck with your Euphoria programming!
