Make a best effort attempt to avoid action cache journal corruption in the event of an abrupt exit.

Do this by implementing a special buffered output stream that only flushes at record boundaries. While this doesn't completely eliminate the possibility of corruption (that would require a different design), it makes it much less likely.
