Subject: Reentrant modules

A module is reentrant if and only if it does not modify itself. To be
put into a shared segment, a module must not do any moves or stores into
itself, because shared segments are write protected. Unless you perform
such useless sequences like

                 L  0,X
                 ST 0,X

this is equivalent to reentrancy.
