Well I think we have the cause - no reason to muse about TSC, suspiciously
fresh RT code and such when plain UI programming blunders in suspiciously old
and unused code deliver a credible explanation.
The mini.tcl backplot redraw procedure issues PAUSE/RESUME sequences during
backplot redraw for no discernible reason.
To see it all in the log:
- turn on on the debugging: configs/sim/mini.ini DEBUG=0xffffffff
- run some ngc file
Issuing EMC_TRAJ_CIRCULAR_MOVE -- (+221,+168,
+0,0.001990,0.000200,-0.100000,0.000000,0.000000,0.000000,0.000000,0.000000,0.000000,0.002446,0.002147,-0.100000,0.000000,0.000000,1.000000,

Outgoing motion id is 1007.
Issuing EMC_TRAJ_LINEAR_MOVE -- (+220,+120,
+0,0.001990,0.000200,1.000000,0.000000,0.000000,0.000000,0.000000,0.000000,0.000000,
+1,1.200000,1.200000,20.000000, +0, -1,)
--- at this point I tick the 'backplot' checkbox _once_, and here come the
culprits, staring at us:
Issuing EMC_TASK_PLAN_PAUSE -- (+510,+12, +11,)
Issuing EMC_TASK_PLAN_RESUME -- (+512,+12, +12,)
Issuing EMC_TASK_PLAN_PAUSE -- (+510,+12, +13,)
Issuing EMC_TASK_PLAN_RESUME -- (+512,+12, +14,)
Issuing EMC_TASK_PLAN_PAUSE -- (+510,+12, +15,)
Issuing EMC_TASK_PLAN_RESUME -- (+512,+12, +16,)
Issuing EMC_TASK_PLAN_PAUSE -- (+510,+12, +17,)
Issuing EMC_TASK_PLAN_RESUME -- (+512,+12, +18,)
I commented out the pause/resume code in the backplot redraw procedure, the
pause/resume sequences are gone; no discernible difference:

Chris couldnt see a reason being there as well; I think that is safe to remove;
this probably should go into 2.5 too after known to work
we learn:
- it is not a bug, rather a feature according to plan, but nobody can tell what
the plan was
- real men dont use comments - those are for whimps
- bigger hammers should be used only after percussive maintenance with small
hammers positively doesnt work
- logging is there for a reason ;)
