module Unixqueue_mt:This module initializes Unixqueue for multi-threaded programs. Make sure that this module is linked as object file (.cmo or .cmx) into the final executable, because this module would be garbage- collected if it were in an archive file (.cma or .cmxa). If you use ocamlfind, this will be done automatically provided that a -thread or -vmthread switch is on the command line.sig..end
