    Default Is shared memory a total mess or am I just being thick????

    Hello all,
    I was going through the ingres code, and found this comment:
    /* Give up if unable to get memory in one minute */

    Arrrrgggg!!!!
    Time dependencies!!!!
    Is this sort of stuff that you would expect to find in production
    quality code?

    Plus, I would like to know if there are any obvious advantages to using
    process oriented databases like PostgreSQL and Ingres over ones that
    use threads(IMHO much cleaner) apart from the fact that they are more
    stable -- if a process crashes, it doesn't take down everything with
    it.
    Practically, software does have bugs, but assume for the time being
    that databases are bug free.

    Is there a constructive reason why you cross posted that "question" to
    non-Ingres groups? Since you don't claim to work for an enterprise that
    has actually been adversely affected by whatever this comment refers to, I
    presume you are just a troll. But you might persuade me you are genuine if
    you try.

    Yes, to know what others have to say about it. If you notice,
    PostgreSQL is also process based -- fork()ing on a new connection,
    while MySql is thread based. It's generally good to know the opinion of
    people who have worked with systems having varying designs.
