I do this in the BC version by inserting an ensure: method context under
the context to be executed.  Then I resume the debugged process and wait
on a semaphore.  The unwind block of the ensure: context signals the
semaphore when reached, meaning that the context above it has finished
and the debugger can take over again.  I also insert a on:do: method
context above the ensure: method context in case any errors are raised. 
The handler block signals the semaphore so the error can be shown in the
existing debugger.  In either case when the parent process is resumed I
remove the contexts I added so you don't see them in the debugger.  See
#runUntil:suppressDebugger: in the BC version for the implementation.

Also, here is another argument for 'thisContext process' over 'Processor
activeProcess'.  The former will be needed when we (someday in the
future I hope) have multiple processes running simultaneously on
multi-processor machines.  In this case, 'Processor activeProcess' would
be ambiguous.
