[omniORB] Lockup on Solaris 2.5.1 with Y2K patch

[Harald Hopfes]

First, even if the 4-byte read is an atomic, the following piece of code,
isn't just a (4-byte) read:
    while(!died)
It conains at least the (4-byte) read, a "COMPARE" and a "BRANCH" assembler
instruction.

Even so, I think it should not be necessary to protect it, but you never know
how the compiler
optimizes this piece of code: So I prefer to be on the save way.

Another question: Do you know the instruction set of your computer and which
kind of optimizations
it uses? I don't!
