texture UV not correct after compute()

[GoogleCodeExporter]

Im using newest version carvelib checked out after jul.

Now, i have handred of pairs of polyhedron ,
every pair ran csg.compute(pairA_1,pairA_2) in a parallel for,
after that,i found that the texture uv vertex attribute is not correct:some 
vertices appears a little bit offset,some vertices get the attribute value 
which not belong to itself.

But its correct when i run them in singlethread.

is it really thread-safe?
