Well, yes and no. It has to do with how ALTER TABLE is implemented in general. Up to the current 5.0, ALTER TABLE always does a full table copy and new index creations (exept of trivial attribute name changes or disable/enable keys). this means that you need twice the size of the table during the ALTER TABLE.

This is going to change. Work for it is in progress, but I cannot guarantee that it will be added to 5.0. It might go into 5.1.
