I don't think that standard fseeko is thread safe. The whole FILE* based
API is suspect.

I think the issue is that when you do a SEEK_CUR/SEEK_END, you have to
take a snapshot of where the current pointer is or the current file
size, so you should lock out other threads while you do those
operations. If you didn't, there could be random unreliability in the
function.
