 The problem goes away when tcsh is run with -F, and thus this bug is 
 probably related to bin/125185 et al.  tcsh under some conditions will 
 modify global state after vfork(), breaking things when the parent runs 
 again.  -F causes it to use fork() instead of vfork() and then all is 
 well.  IMHO -F should be made the default.
