Mutual exclusion in Emacs

Hi ! 

How  is concurrency  managed in  Emacs?  I know  there's no  threading
support, but since you can launch several asynchronous processes, with
process sentinels, is there a risk that a process sentinel preempt the
non-process-sentinel  code   being  executed,  or   another  processes
sentinel. 

If so, is there a way  to guaranty mutual exclusion if all the process
sentinels access a common ressource? 

Thanks for your help,
