I will have to take a look next week, but if this patch behaves as
described, my objection is lifted.
This may be a good starting point for doing our own internal
implementation that does cross-platform support since it gives us an
easy starting path - reimplement the posix_ routines ourselves, but
let's at least get this one in.
However, if we are nearing a 1.4 release, I would say this is probably
1.4.>1 material as opposed to 1.4.0.
