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.

I'm curious which features you feel are esoteric and cool but unused?
