Silicon hangs if smt code sent to Z3 isn't indented

Silicon requires that multi-line constructs (such as axioms) be indented, such that only the first line is without an indent. If modifying e.g. the preamble, and this is not respected, the tool hangs waiting for an acknowledgement from Z3.

There should be some kind of timeout mechanism for this iteraction.
