SubjectShared memory

I contacted Alan Cox about a number of behavior issues I observed using
socket system calls. I also would appreciate some comments on the
behavior I observed using shared memory. He suggested me to send
this issue to you.

Your comments would be greatly appreciated,

Best regards,

Michiel Bacchiani.
