Namespace collision -- no. jQuery registers itself globally as '$' and
'jQuery',
and neither GWT itself nor our GWT code use those names anywhere.
+1 this is my understanding as well.
However, there can be behavior conflicts. I'm currently debugging a problem
where tooltips aren't destroyed when grid refreshes happen. The jQuery widget
doesn't 'know' that the GWT widget it's attached to was destroyed :(
In cases like this one, could we close/destroy the tooltip via GWT JSNI code?

First-load time will be negligible and cached.
Mass-use of bad selectors could decrease browser performance. I think we
should
very rarely use jQuery in oVirt. Usages of it should be very justifiable.
Exactly, any direct use of jQuery should be justified by a solid reason.
