Flare: low, slow, and uncoordinated? I'd like to rephrase the question:

Often I forward-slip on final right right rudder.  During this time, I use the ailerons to keep the aircraft headed down the center-line; the aircraft's bank varies slightly from left wing down, to right wing down.

At some point during this procedure, I have right rudder in and a slight right bank.  I believe this is a skid; Is this something I should worry about?  I would very much like to avoid skidding at all times, especially on final!

Previous question, for reference:

Assuming there is a crosswind and the pilot executes a crabbed approach, during the flare the pilot is going to have to use the rudders to avoid a side-load.   My understanding is that this will result in an uncoordinated flying condition and is prone to stall-spin.

However, this (the flare) does not seem to be much of an issue among pilots.  What am I missing?  How is this any different than a skid?
Crosswind landings are always uncoordinated. I'm not familiar with big jets, but I believe they simply kick the rudder to align the nose with the runway and let the momentum carry it in the right direction until it touches down, but I might be mistaken here.

In a smaller aircraft (like a piston single) you're taught to drop a wing into the wind and effectively land in a side slip.

This is all perfectly safe, the dangerous situation you're talking about is a skidding turn, where you apply too much bottom rudder, letting the 'inner' wing slow down to the point of stalling. This only applies to an actual turn however, if you're flying straight, coordinated or not, there's still more or less the same airflow over the wings. You could however experience other aerodynamic effects where fuselage and airfoils effectively perturb the air for other airfoils and might cause a wing drop or pitch change, but it depends on the properties of the aircraft.
