Thanks for the docs improvements!

You might be able to lift useful fragments from the comments (e.g.;a=blob;f=src/x86_64/Gtrace.c;h=446610cbdf4dff330b690232656743ccbb708c31;hb=HEAD#l333).
The user-visible unw_backtrace() API does the fallback mentioned

Perhaps call out on the man page that unw_backtrace() is async signal
safe and suitable for use within malloc(), profilers and other tricky
corners? The system backtrace() may not be - often isn't. If you do
mention this, perhaps also mention under BUGS a risk of deadlocks in
_dl_iterate_phdr() and crashes from bad unwind info? These are general
properties of libunwind, not of unw_backtrace() specifically.

My preference would be "Lassi Tuura, Fermilab <address@hidden>".
