| Well, it sort-of does.  Csh's under SysV are usually sub-sets of full-blown
| BSD csh's, and don't behave the same.

Sorry, it's a BSD-vs.-Sys5 issue.  csh doesn't act the same under System V
because System V doesn't handle process groups the same way BSD does.  BSD
process groups are used to implement job control; this is why a backgrounded
process in a job-control environment (like csh) detaches from the terminal.
