You can make your plots more robust to can't determine bounds errors
by including an `invisible-rect' or `invisible-rect3d' renderer in the
plot, with fully specified (i.e. non-#f) bounds. The plots' bounds will

This contract intends to check if the rest argument is a) a list of symbols
and b) has an even number of elements.
The only difference (apparent to me) between proc1 and proc2 is the
ordering of the contract predicates. Yet they give different results --
proc1 seems to ignore the even? condition.
Use and/c
Currently it's just checking if your function is truish (it is) and then
returns the second contract as the result of the expression.

In this case you would have a separate thread that mediates all access to
one of these channels and that makes it easy to get such concerns right.
