Re: System call support in reversible debugging

[Hui Zhu <teawater@gmail.com>]

This is a old query.  For now, this munmap just can let prec ignore
some memory change record entry.

You can answer 'no' then inferior will keep exec.  Most of thing will
be find.  :)

Maybe we need update this query looks not so scary and  do some other update.

Thanks,
Hui
