Thanks for the detailed analysis that indeed makes sense in the general case.
In this specific example introsort_loop is not inlined just for choice of a gcc
heuristics.
My understanding was that with -fvisibility-inlines-hidden I made the 3
move_median_first and the 3 introsort_loop functions "internals" to the library
and therefore neither visible nor preempt-able.
maybe they need to be declared "inline" in gcc or even "hidden"?
In any case I do not think that they are ment to be preempt-able!
