[E-Lang] yet more on security manager

[Marc Stiegler]

In the days of jvm 1.1.7, we found this not to be true: the IBM compiler
didn't cut it.

Today, I wouldn't be surprised if this were true, though I haven't been able
to use IBM jvms enough to really form an opinion, only enough to know that
they work a lot better than they used to  :-)
