My first job our software ran on Windows, Linux and Mac. This was well before OS X, and I was horrified to learn that all the 'multitasking' in the Mac version was a message pump and longjmp calls all-the-fuck-over. Decode a few blocks of gzip compressed data, then check for network traffic. Then decode part of a JPEG. I don't know how they did it.

The were, however, the only people in the world with multiple monitors (outside of SGI).
