We discussed this on irc a bit, but for the record, I think there are
latent bugs that this patch will expose.

For example, several tests in gdb.base use the same executable name:

    barimba. egrep 'set testfile.* "break"$' *.exp
    completion.exp:set testfile "break"
    condbreak.exp:set testfile "break"
    define.exp:set testfile "break"
    ena-dis-br.exp:set testfile "break"
    environ.exp:set testfile "break"
    info-proc.exp:set testfile "break"
    maint.exp:set testfile "break"

Jan went through and fixed bugs like this for the current split.
