Yes, there are ;-) In particular, PyTables itself does not support low-level locks yet. Lock support is critical when several processes are writing to the same file at the same time. So, you should either wait until CSTables is ready or provide this lock by yourself. On the other hand, there is no problem with several processes accessing simultaneously in read-only mode to the same file at the same time.
