This issue did NOT affect the version of the systemtap package,
as shipped with Red Hat Enterprise Linux 4, as that version
uses completely different underlying logic for what is worthy
regarding to modules removal.

This issue affects the versions of the systemtap package, as shipped
with Red Hat Enterprise Linux 5 and 6.
