#368 is still not full resolved.
I am still getting the error with 2.5.7 where the fix is applied.
[Errno 2] No such file or directory: '/tmp/MAIN.tmp'
The thing is that I have many independent and unrelated processes creating temporary Ram-based indices. /tmp/MAIN.tmp' is being deleted at times while other processes are using it or are trying to delete it.
Using tempfile and a real temp directory would be much safer IMHO
