Greatly improve /proc/PID/stack by tracing the ebp frame chain.
I also added a generator cache to FileHandle. This way, multiple reads to a generated file (i.e in a synthfs) can transparently handle multiple calls to read() without the contents changing between calls. The cache is discarded at EOF (or when the FileHandle is destroyed.)
