Yes, that can be made to work. V8 unwinds the JS call stack until C++ code calls isolate->CancelTerminateExecution(). Assuming your execution contexts don't interleave (context A can't call functions from context B), then all you have to do is place CancelTerminateExecution calls in the right spots. If they do interleave, well, you're in for a rough time. No real way to make that work. -- -- 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.
