[reSIProcate] Dum threading request

[Steve Robichaud <srobichaud@xxxxxxxxxxxxxxxxx>]

Hi,

I believe that previously (quite a while ago) someone posted a question 
about adding a method named DialogUsageManager::processNeeded() that 
returned the results of mFifo.messageAvailable().  

Is there any chance that a method such as this could be added to 
DialogUsageManager?  Would this be worthwhile to anyone else?

The reason I ask is that I found it simpler to write a DumThread type 
class that just checks for messages and then posts an event semaphore.  
This way the (different) thread that is running 
DialogUsageManager::process() watches the event sem before calling 
process() which simplifies the thread synchronization/context switching.

Thanks,
Steve Robichaud
