vsz_limit

[Joan Moreau]

For machines with low memory, I would like to detect how much ram 
remains available before starting indexing a mail, so I can commit 
everything on disk before the ram is exhausted (and break the process)

I tried to put a "fake" allocation to test if it fails, (so it can fail 
separately, and I can "if ram remaining is above X") but the is really 
not clean
