Hello all,

Coming from python, specifying "threadsafe: true" creates CPU-bound 
incoming http request threads, which limit an instance to handling one http 
request thread using the CPU at any time.  On the other hand python does 
allow handling of parallel I/O within a given http request thread.  This I 
believe means python http requests threads are only concurrent and switch 
between threads during a blocking operation, not execution in parallel.

I would like to know if Java is the same as python, or if specifying 
<threadsafe>true</threadsafe> means each incoming http thread is executed 
in parallel.

Is the following assumption correct?
Assumption: That would mean Python incoming http requests are handled 
concurrently, and python async api's are handled in parallel, and that Java 
incoming http requests are handled in parallel, and Java async api's are 
handled in parallel.

Thanks in advance to anyone who can shed light on this.  Please let me know 
if my assumptions of GAE Java are correct.

Best
