Remember that one apparently has to _export_ HISTFILE at that spot.

`unset HISTFILE' works in the shell in which you execute it, but if
you start a subshell, the subshell will re-initialize HISTFILE to its
default value.  If you do `HISTFILE= ; export HISTFILE', the subshell
will not re-initialize HISTFILE, which will remain null.  At least all of
this is the case for bash, including when invoked as sh or `bash --posix'.
Solaris2.8' sh does not seem to keep history at all.
