It *can* change with a texexec, imagine using the page number in the MP
code, for example. More serious problem: even if texexec calculates the
checksum, then how would the TeX macro code know its status without
first
calculating a checksum itself? It needs to compare two checksums: one
from
this run against the one from the previous run.
