If you've got facts and technical explanations to show that
'--fast-read' is somehow critical I'm sure we'd all like to hear them.
I'm quite curious as to what such reasons could be myself.

Technically speaking though it seems pretty clear with even minimal
analysis that '--fast-read' is simply an unnecessary optimisation.  No
functionality is lost without it, and it could even safely be
implemented as a no-op.  I don't have it in my implementation and I
haven't encountered any problems whatsoever.  OpenBSD doesn't have it in
theirs and I've not found any online reference to any problems over
there either.

I.e. any claim that '--fast-read' is a necessary feature before pax can
successfully replace GNU Tar seems to be, technically speaking, wrong.
