Ah, I think I see the reason.  The `finish' command, which you were
comparing against, is strict.  But with this implementation, `collect' is not.
I think a good part of that factor of 5 is the time spent checking for
breakpoints.  Try setting `cmd->MR_trace_strict = TRUE' there. 

Note that this is in code that you didn't include in your original 
cut-and-paste snippet.  If you want other people to debug your problem
it always helps to post a full diff.
