[ltt-dev] userspace debug symbols in traces

I just used LTT to debug a threading problem on a userspace app that
was not scaling well. It was great to see when the systemcalls and
scheduling happened but I notice I could possibly go one step more.
With the systemcall entry or the IRQ entry I see that we have the IP
from the userspace process. What would interest me is if we can somehow
use LTTV to resolve the debug symbols those IPs point to in the
userspace process. Has this been tried or implemented and is there
anything I can start with to do this?
