Hi,
Perl historically has supported Sfio, but I haven't heard of anyone
trying to build perl with Sfio support. The last test I found in the
archive with Sfio enabled is about a decade old, and I assume all I
can assume it is as broken as our stdio support, and given that it was
never updated to support our own better-than-stdio system that may be
an optimistic assumption. Quite frankly I can't see any reason not to
completely drop our current implementation.
What would make sense is to reimplement it as a PerlIO layer. A naive
implementation shouldn't be very hard, though I'm worried how it will
interact with delayed signalling system.
