Comment 15 for bug 1452005

I don't think that this is a question of a future quarantine process.
Grace-full recover such an error should don in both cases.

By the way: Does it make sense to use mmap for very fast IO which introduces the SIGBUS risk in one place and
pipe the stream over a process borders in an additional step. Probably not.
As far as I remember all crashes we had where meta data related. The sample file IO itself seams to be pretty stable.
So we need to consider careful the performance gain of such an external process.
