So, ionice was introduced in 2.6.13 then? Hm, that is actually a pretty 
unwelcome restriction. On the other hand, the code is used for strigi which 
can be deactivated.
In any case I would not really know how to make the app pace itself regarding 
to IO. I am not even sure if its worth the effort at the moment.

I would tend towards Alex' proposition to ifdef the calls the easy way, so it 
compiles everywhere and uses the lowest priority possible.

So that would mean something like

#ifndef SYS_ioprio_set
return false
#endif

Cheers,
Sebastian
