Stas,
it probably depends on the linker used to create the clipper app, here we use
blinker to create a protect mode application, and this application calls
src/base/async/int.c function ms_dos case 0x2C.
In 1.1.3 (which is the dosemu we use) I had to make the changes I told you, and I
use hog_threshold(0) to have the clipper app to give back all the time it doesn't
use.
But, on OS/2 I have the possibility to give back the rest of my cpu time slice,
while in linux it usleep()s a fixed amount of time and this makes the program
sluggish without my changes.
regards.
