Veeeery slow until a static error is raised on Windows

[Gabriel Petrovay]

Using the following library module (lm.xq)
----------------
module namespace lm = "http://foo";
import module namespace bar = "file://bar";
----------------

and running:
zorba.exe --compile-only -l -f -q lm.xq

Zorba requires almost 3 seconds to terminate on my Windows machine.

(for a normal syntax error Zorba ends almost instantaneously, so it's no the zorba srote dll loading)
