FileCache is not thread/multiprocess safe

[GoogleCodeExporter]

As noted in the comment in the file, the FileCache may not behave well in the 
presence of many threads/processes all writing to the same cache.

The patch attached fixes this (at least for POSIX systems).

Looks good, have you tested this under windows?

Sorry, no - and I won't be likely to any time soon, I'm afraid. In principle it 
should work, it just won't be thread safe on Windows - but the existing cache 
isn't anyway, so it oughtn't to be any worse. Untested, though.

Did you mean to close this? I can't see any code to fix it in the repository.
