I know, I know.  It would be a horrible waste of money to give them to
me in terms of raw cost benefit, EXCEPT of course that to me they'd be
FREE, and it is hard to beat that for cost benefit;-)

So I guess you can ask for them instead.  At least the Netherlands is
closer to the UK...:-)

 In a little known book of ancient wisdom appears the following Koan:

    The Devil finds work
    For idle systems
    Nature abhors a NoOp

 The sages have argued about the meaning of this for megacycles, some
 contending that idle systems are easily turned to evil tasks, others
 arguing that whoever uses an idle system must be possessed of the Devil
 and should be smote with a sucker rod until purified.
 I myself interpret "Devil" to be an obvious mistranslation of the word
 "Daemon". It is for this reason, my son, that I wish to place a simple
 daemon on your system so that Nature is satisfied, for it is clear that
 a NoOp is merely a Void waiting to be filled...

 This is the true Tao.
