When writing that reply I was not thinking clearly enough: if you are
getting a long delay when starting in the middle of a movement and *not
*at the end then it must be that Denemo is doing something during that
delay. What might work is to run it under the debugger and use Control-
C to interrupt it during the long pause and then the command "where" to
find out which function it is in at the time (then "continue" and
interrupt it again). Doing this a few times may show up some loop in
the Denemo code (there will be more sophisticated ways of doing this
I'm sure but this may do ...)
