I wasn't referring to any part of the docs in particular. If I remember 
correctly, I came across rt_task_set_mode(...) in the API documentation 
and naively assumed that a task could be set to secondary mode when it 
is expected to frequently trigger mode switches (e.g. data logging, 
graphical user interface). Perhaps a short note could be added to the 
function's description to the affect that the T_PRIMARY bit should be 
modified manually only in exceptional cases. Or maybe I'm the only one 
who got confused!

In any case, thank you for these clarifications!
