All MT have vents someplace they may not have been readily obvious but they are there. You are correct that a bad driver can over heat a clutch but even the very best creates heat. The whole way they work is through friction after all. The venting is there to permit the dust that is created to be removed. Every time you use the clutch you create a small amount of dust and if that was contained to the housing you would eventually have everything gummed up solid.
At least that is what I was told by the guy that rebuilt the tranny in my 55 Chev when I asked about the gaps in the top and bottom.
