I don't think ChannelDefs.pm was meant to be kept in sync, unlike
Channels.pm.  Those have diverged too, of course.

Well, the threading code in Automake was added only to allow to create
Makefile.in files in parallel.  I added some helper code in the channel
processing to allow to guarantee that automake's output does not differ
between threaded and non-threaded execution.

That said, I am still hunting down the occasional weird issue (usually a
segfault) with older perl versions on some system.  I was going to just
wait for feedback when the test release is out, to have better
statistics on the bug, but it means you might not want to hurry up in
merging the code.

Cheers,
Ralf
