Re: Is POE thread safe?

I think you misunderstand.  POE synchronously calls all event  
handlers.  It's up to other modules or applications to introduce  
preemptive concurrency.

As presented, the examples you've shown don't introduce preemptive  
concurrency, so there should be no problem with them accessing  
"shared" resources.
