I\u0027ve manually inspected all the callers and added a\nScopedHeapLock where I think one is necessary. In manual testing, this makes\njdb a lot less prone to locking us up. There still seems to be a problem with\nthe JDWP VirtualMachine.Resume command, but I\u0027ll look at that separately. This\nis a big enough and potentially disruptive enough change already.\n\nChange-Id: Iad974358919d0e00674662dc8a69cc65878cfb5c\n"
