Interesting question! V8 doesn't use extra-process resources like named shm segments so I don't see why it wouldn't work. Not quite the same thing as "officially supported" but there are no technical blockers that I can think of. Perhaps one caveat to keep in mind: V8 is pretty greedy when it comes to reserving virtual memory. It won't be a problem on 64 bits platforms but on 32 bits you might run out of address space with two V8 instances. -- -- v8-users mailing list v8-users@googlegroups.com http://groups.google.com/group/v8-users --- You received this message because you are subscribed to the Google Groups "v8-users" group.
