Subject: [PATCH 1/1] attach time-independent traces to processes when the
 executable is called replay. It takes only one argument that is a file
 listing the traces to attach. If there is only one trace in this file, all
 the processes try to find their own actions in it. Otherwise, they have their
 own trace to read.
