[elephant-devel] Re: Postmodern: Removing the ABORT restart

[Ian Eslick]

What is the status of this bug/issue?

I'm losing track of all the bugs in the system.  It would be very  
helpful (and your bug is less likely to be forgotten) if you could  
file Trac bugs against 1.0 for these reports?

It's easy enough to get a common-lisp.net account to sign onto Trac.

Thank you,
Ian
