The shake down will be telling people to do a cvs update -d 
src/gdb/testsuite/gdb.cp.

The release isn't been held up for the gdb.cp rename, it happened to 
slip nicely into the schedule.  If it's not done by Sunday, I can easily 
do it myself.  The bottom line is that if it screws up, and the 
testsuite is a brick, no one will notice. GDB on GNU/Linux will still work.

On the other hand, if vfork/exec breaks, GNU/Linux breaks and everyone 
notices.
