"tcsh hangs when invoked from gdb"?

gdb uses ptrace(2), which breaks the process hierarchy - the debugged
process is reparented to gdb.  When the debugged process forks and gdb
attaches to the child, the child will seem - from the parent's
perspective - to disappear into thin air.

This has never worked correctly in FreeBSD and is completely unrelated
to tcsh, so you can get off mp@'s back already.

Fixing it is hard.  I've tried.  It seems easy until you realize that
you need to rewrite most of kern_wait().
