Not in this case since the funit-breakpoints uses the SA_NODEFER workaround. The
test does check that SIGTRAP and segfaults not caused by frysk itself are
propagated correctly. See bug #3997 for a discussion about this.

I'll checkout the branch and test first against the simpler unit tests first.
TestTaskObserverCode which only does a set breakpoint, run, check that it got
hit (maybe expand it to then continue running again), the
TestTaskObserverInstruction test, the TestTaskObserverInstructionSigReturn and
the combined TestTaskObserverInstructionAndCode tests. If those work then we can
proceed with the all singing and dancing TestBreakpoints which is really a
combination of all those tests.
