--- Comment #3 from Frank Ch. Eigler <fche at redhat dot com> ---
The difference appears to be the presence or absence of an STP_EXIT packet
being sent to the module.  In the staprun monitor.c-'q'-invoked cleanup, there
was no STP_EXIT packet, thus the cleanup_module() /
systemtap_kernel_module_exit() path only was taken.  This does not include the
STP_EXIT handling (systemtap_module_exit), which is a bug.
