If you make it sleep shorter time or make your machine busier, you will observe your original problem with named pipe (or any other methods). A Unix pipe has at least 4k buffer size and I don't think there is a way to make it smaller. Without a way to reduce the pipe size and not able to modify the streaming code, I see no way to solve your problem.

intel_panel_fitter(1)					      General Commands Manual					     intel_panel_fitter(1)

NAME

       intel_panel_fitter - Change the panel fitter settings

SYNOPSIS

       intel_panel_fitter [options]

DESCRIPTION

       intel_panel_fitter  is a tool that allows you to change the panel fitter settings, so you can change the size of the screen being displayed
       on your monitor without changing the real pixel size of your desktop. The biggest use case for this tool is to work around overscan done by
       TVs and some monitors in interlaced mode.

   Options
       -p [pipe]
	      pipe to be used (A, B or C, but C is only present on Ivy Bridge and newer).

       -x [value]
	      final screen width size in pixels (needs -p option).

       -y [value]
	      final screen height size in pixels (needs -p option).

       -d     disable panel fitter (needs -p option, ignores -x and -y options).

       -l     list current state of each pipe.

       -h     prints the help message.

EXAMPLES

       intel_panel_fitter -l
	      will list the current status of each pipe, so you can decide what to do.

       intel_panel_fitter -p A -x 1850 -y 1040
	      will change the pipe A size to 1850x1040 pixels.

       intel_panel_fitter -p A -d
	      will disable the panel fitter for pipe A.

NOTES

       In the future, there will be support for this feature inside the Linux Kernel.

       Machines older than Ironlake are still not supported, but support may be possible to implement.
