I think that 3720 should be considered a must-fix.  If people use stream
I/O in security-critical programs, this kind of buffer overflow could lead
to root exploits in programs that would be perfectly safe with a
correct iostreams implementation.  I don't think it's ethical for us to
ship with such a bug.

Also, it shouldn't be hard to fix it once agreement is reached on how.
All that's needed is an upper bound on buffer size.
