[Bug general/3985] New: What is lib.unwind.StackTraceCreator.arg_hash

["cagney at redhat dot com" <sourceware-bugzilla at sourceware dot org>]

It's comment is:
    /* arg_hash maps long values corresponding to the addresses of an
     * UnwindArgs object and its CBarg and UPTarg fields, to the
     * UnwindArgs object itself.  This enables us to choose the right
     * argument to pass to callbacks even when one callback calls
     * another.  */
which makes me wonder if the binding is single threaded.

Can this bug and the comment be updated with a more detailed description.
