Typically deadlocks are more likely to be caused by your own code,
rather than the underlying frameworks.
This assumes you're using Wonder/WO/EOF in a thread-safe manner.
i.e you are taking the necessary precautions for EOF (like turning
off shared EOs, auto lock/unlocking of ECs, etc).
Broadly speaking, Scala is safer to use than Java for developing a
concurrent request handling app because of its lack of static
variables
I'm not sure why static variables would be necessarily anti-
concurrent? It depends on the type of variable, no? e.g., a static
string is immutable. A static nsformatter is not re-entrant... etc
and methods, use of separate mutable/immutable datatypes and
collections, etc.
Using Ajax (i.e asynchronous communication) with WO is where the
need for concurrent request handling and better thread-safety come
in...
