Test times of untimestamped streams are bogus

Test repository applies timestamp information to streams using the AutoTiming result decorator; this is done behind the demultiplexing logic. As such, if a stream is untimed, the automatically applied timing data will be wrong - it will show all tests being near instant, due to the action of the demultiplexer. We need to timestamp incoming streams before they hit the demuxer, either in a separate process (avoiding GIL issues), or more coarsely but probably acceptably, just ahead of the demuxer in process.

The following patch takes the latter approach:=== modified file 'testrepository/commands/load.py'
