Description Phil Muldoon 2007-11-21 10:38:26 UTC 
The nexti command should not be even allowed to run on a corefile process, and
checks should be placed to check for proper usage. Current usage:

[pmuldoon@localhost frysk_bin]$ ./frysk-core/frysk/bindir/fhpd core.11108
Attached to core file: /home/pmuldoon/frysk_bin/core.11108

(fhpd) nexti
