vyzo
257423e917 fix view waiting issues with the WaitGroup 
We can add after Wait is called, which is problematic with WaitGroups.
This instead uses a mx/cond combo and waits while the count is > 0.
The only downside is that we might needlessly wait for (a bunch) of views
that started while the txn is active, but we can live with that.

which would not wait for the view to complete.
