I'll continue working with the patches and try to get tmpfs support
added here soon.
Also, attached is a simple cleanup patch that you might want to fold in.

Would you mind testing the following patch? It seems to resolve the
issue, but I've not yet run it through my test suite to make sure it
didn't break anything else.
No problem, I will try it this evening.
Is this problem related to all 32bits arch ?
t more testing would be of course appreciated.
