I've been trying to use it on x86-64 without much luck. The profiles all show
functions which are their own callers and have no other callees.
I'd like to blame redhat, but I've pretty much convinced myself that they are
innocent this time.
Does it work well on i386 linux? What was the earliest version of linux which
included working support?
I'm going to try to submit a more formal bug for this, but first I wanted to
ask what might be a FAQ.
