Launching background job from Ada.Real_Time.Timing_Events

["Alejandro R. Mosteo" <alejandro@mosteo.com>]

Hello all,

I'm stuck with something not that strange, so I guess I need another 
viewpoint on it.

I want to trigger, in the future, a possibly long computation in the 
background. For that I had thought of using the built-in Real_Time events.

My idea was to queue the job when the event is triggered, and to have a 
worker thread waiting for jobs in the queue. However, I've just realized 
that the event handler is itself a protected action, so I can't call 
another potentially blocking enqueue from there.

Any ideas? Basically, how to trigger another task (without creating it) 
from within a protected handler?

Thanks,
Alex.
