hmmmm parallels can be tricky. Analogy thinking can be misleading.
In essence, yes the "track" becomes free to carry another train. we have
suspended the association between the train 1 and track 1 and can put train
2 on track 1 (another method invocation with another Tx Context running on
that same thread). The "task" completion callback (the Synchronization
interface or XA as well) talk to the "transaction" and associated listeners
(wrappers, Ressource man etc ) but not to the tracks (the thread)... the
train tracks don't care that you completed your final journey in another
continent.
The train doesn't stop its voyage, it is not "suspended". The thread is free
to do something else. (in case of rmi = die AFAIK, rickard? rmi pools of
thread re-use?)
JTS "suspend" is suspend the "transaction", aka, the voyage (like freeze the
train in time)
JOnAS tm.setPropagationContext(null) or jboss2.0 tm.disassociateThread() are
the "suspension" or more precisely "association/disassociation" mechanism
between thread-tx we are looking for..
