You can do that on Linux too, with setting LD_PRELOAD to a shared library
full of functions that you wanted to use over their shared library
versions. Glen here, was messing with something that did something similar
in Kernel space - overloaded every open() system call, to printk("Someone
is opening file %s", filename) etc.
There are just as many messed up people coding operating systems now, as
ever.
