  1. Merge branch 'perf-help' into dtrace 

    This adds a module PERF-HELP that you can REQUIRE, it provides a function
CCL:CREATE-PERF-MAP to export a symbol map supported by OS level tracing
frameworks (for now only Linux x86).

On Linux, when the map is present (as a file in /tmp/perf-<pid>.map) perf(1)
will use it to reconstruct stack traces.

Ideas and code are mostly inherited from Gary Byers. Isn’t it great when you
set out to do something and find the hard parts already done? <3
