Wrongo.  SunOS "dbx" has "attach", but that's because SunOS "ptrace" has
PTRACE_ATTACH.  4.xBSD's "dbx" doesn't have "attach", because 4.xBSD's
"ptrace" doesn't have PTRACE_ATTACH.  Vendors other than Sun also offer
"dbx", and they may or may not have "attach".  I don't know which
version of "dbx" you mean by "standard 'dbx'", but not all versions have
"attach"....
