| From: David Collier-Brown <davec-b@rogers.com> | mbox works well if the person writing the code knows Unix V6 primitives. If | not, they can fail (;-)) | For messages larger than the atomic-write size of the filesystem, mbox can | have a race condition, as it depends on atomicity of writes to end-of-file to | append a whole message at a time. I'm pretty sure that the programs I currently use to access mbox files use locking. procmail uses lockfile(1); I don't know if alpine uses the same locking.
