I want to save power.  no_sleep_autoadjust=N and iwconfig wlan0 power
on does a good job of that.  I assume that no_sleep_autoadjust
defaults to Y because it's still not reliable (and I seem to have seen
a few networks where it causes occasional problems).  So I'd like to
be able to toggle it at runtime, file bug reports when it fails, but
still be able to use the networks it fails on :)
