debugging.

Eric has wrote a nice little article about kernel debugging, which I found to be a rather nice look at debugging in general. When systems become extremely complex, the chances of some small issue rearing its head as a major problem increases. I say small issue, but mean bug, though the bug itself may be simple or trivial at its root getting to that place is more often than not a trial in itself. How many routines could possible have changed a value? Are we sure that the memory we're using is "safe". Even in a garbage collected world can a programmer really be certain the memory in use is trustworthy? With that annoyance in mind, consider the vast sea of libraries availible to programmers.
