Here's a revision, I missed one case - single stepping off a breakpoint 
when there's a signal.

Now the interesting bit.

i386: single-stepping over a signal handler fails
ppc: single-stepping over a breakpoint (with signal handler) fails

I suspect they are the same underlying bug.

Tested on i386 (FC2 with a `fixed' kernel) and PPC (with a `fixed' kernel).

Still ok?

`fixed' refers to a kernel that can correctly single-step a system call.
