Robert Munteanu commented on SLING-10441:
-----------------------------------------

If we end up using a dedicated thread pool I would say (as a personal opinion) 
that the deployer must make sure that the Sling Discovery bundle has the 
required resources, so we should:

- document that the Discovery bundle requires a dedicated thread pool for 
infrequent but time-sensitive tasks
- recommend this pattern in the commons threads / commons scheduler 
documentation for time-sensitive tasks

> make discovery independent from scheduler thread pools

> Currently discovery uses the commons.scheduler for a few but mission critical 
> cases. Since the commons.scheduler doesn't guarantee timely execution - eg 
> when the corresponding thread pool is full - discovery should become 
> independent of commons.scheduler.
> The easiest solution is to spawn {{new Thread}} in those few cases. This 
> shouldn't be problematic since these activities are not happening on a high 
> frequency and are only short-lived.
