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, -- Matthieu
