Cherry-picking phoeagon's commit fb0a18d

1. Change some of the "assert type() == int" statements into "assert
isinstance(, (int, long))". Apparently, this is needed for the tool to work in
some Python environments (probably for 32-bit environments).

2. Phoeagon complained that setting "use_cached = False" during replay produces
weird behavior. Haven't tried reproducing the problem, but turning it off so
that first-time users are not discouraged if there is such behavior.
