I guess I'm talking about a separate program that does 
essentially a huge superset of gdbreplay's current
functionality, 
using the same input logfile as is currently used by
gdbreplay.

In a sense a replacement for gdbreplay, but the existing
gdbreplay doesn't have to go away, if it serves a purpose.

Yeah, well -- show me an alternative.  Gdbserver?  Maybe.

In principle the stuff I'm writing could go into gdbserver
or some other debug-agent codebase.

This is an extension of a different project I was working
on,
using rda.  It just occurred to me that I could make it use
the log files that are used by gdbreplay, and make them 
suddenly really useful.

I've used it for testing... like once every two years.  If
it took any
more maintenance than it does I'd probably have dumped it by
now, but
it's nice and simple

Maybe.

There isn't any good GNU alternative that I know of.  But
RDA isn't
much of an alternative either if you want to make a GNU
program.
Just saying.

Wouldn't you need a completely different sort of log file?
