I see that some workers remain in a pending state for about a minute, 
after which the same amount of workers that are in pending state 
register as new workers, and the number of available workers gets back 
up to what we had to begin with.  I think I removed a few months back 
the mechanism that went through periodically and cleaned up the pending 
workers... which is leaving them stuck in a pending state in the logs.  
I'll try to add that back in. 

Now, for the real problem why these workers are ending up in a pending 
state, and never going to a running state, we need to do more debugging.
