Ahh.  My, approximately second program that I wrote on Solaris, in C,
was a program to brute force solve a math problem.  I solved it also,
but got points deducted for inelegentness.  Anyway, when I ran one copy
on an IPX, the machine got rather sluggish.  And I made the mistake of
leaving it -r-xr-xr-x.  So some punk gets the idea of using it to knock
another punks machine offline.  He runs 100 copies of the program on an
IPX and brings it to it's knees so hard that the machine had to be
stop-A rebooted.
