AFAIK on GNAT they are OS threads. However, when implementing my own green =
threads (for a virtual machine) I've found out that assigning twice than th=
e available tasks than CPU cores (or, available hyperthreads if HT is on) f=
or some  reason increased performance, so it seems worth experimenting rath=
er than relying on theoretical assumptions.

Anyway, on my machine running GNAT 4.6 on Linux tasks easily max out all av=
ailable cores at 100%.
