Well, there's a difference between frameworks and applications. At
least in GNOME e.g. we've been generally good at picking up and
transparently taking advantage of Linux-specific stuff where possible
like splice() in g_file_copy(), and in this cycle I'll probably end up
using signalfd() to fix a long standing race condition.
