Hi,

We've seen this recently on Solaris / ZFS also.

Same thing.

This is harmless - maybe xfs and zfs just have more overhead, so they do 
not fullfil that assertion.

hashindex is a Cython module. For releases, we bundle the resulting C 
source, but that needs to be compiled (and usually is, if build deps are 
present).
