In the Bourne shell, the sequence of commands

     export KILLIT
     unset  KILLIT

will remove KILLIT from the shell's environment altogether.  The closest I
can seem to come in the C shell is

     setenv KILLIT ''

which defines KILLIT to be the null string, but does not remove it.  Am I
stuck with:

     exec sh -c 'export KILLIT;unset KILLIT;exec csh'

???
