deadlock

Deadlock detector sample - http://www.onjava.com/lpt/a/5246 http://www.javaspecialists.eu/archive/Issue130.html http://www.javaspecialists.eu/archive/Issue147.html

Deadlock problem, to be honest I haven't encounter much issue about this, may be I already design my code good :-) Anyway keep as reference and see if it useful in the future

Transactional memory

Someone say the basic idea behind transactional memory is that memory is shared by all the threads in a read-only manner. Threads modify data by "committing" objects to shared memory. If a thread commits on top of a dirty object then it has to "rollback" and retry.
