There are other reasons why a process instance is not guaranteed to work in a synchronous manner on the calling thread, such as timers, human intervention, ESB invocations and possibly others.  In general this is not something that the invoker of the process instance can control.

There are also issues when using transactions, especially if a transport such as JMS is used, and resource usage/contention/scaling.

These are all issues that we take into consideration with the current approach.
