Hi -

Just in case $SUBJECT test case sometimes fails for you, don't worry,
be happy.  It means that systemtap is simply exhausting some resource
while preparing to probe all .. er .. 427598 (on fc6 x86-64) .. probe
points that the current translator expands from this:

    probe kernel.function("*") {}
    probe module("*").function("*") {}
    probe kernel.function("*").call {}
    probe module("*").function("*").call {}
    probe kernel.function("*").return {}
    probe module("*").function("*").return {}
    probe kernel.function("*").inline {}
    probe module("*").function("*").inline {}

The eagle-eyed will notice that we're double-counting to some extent,
since #(FOO.call) + #(FOO.inline) == #(FOO).  The resulting .ko is
rather hefty.  That is good, since it will force us to build up the
blacklist a little more (bug #4307?), and since it will keep one from
just goofing around trying to instrument every 10-100th instruction in
the kernel.
