Hey
I think we need to keep an eye on this and be ready to check ltrace if
this gets merged
Cheers

strace works fine with this patch applied and, looking at the
sources, it doesn't use the SINGLESTEP request. As for ltrace,
it *does* use SINGLESTEP but it can use PTRACE_SYSCALL instead
(indeed, it does this for sparc, ia64 and mips). ltrace doesn't
have code for checking the ptrace return value so I'd say it's
their bug.
