Thanks for your vote of confidence, cybear...

Unfortunately, from my inexperienced point of view, basic and signal handling are mutually exclusive - it's pretty complex. I need a few more attempts and a little more time reading the docs before I'd consider writing a tutorial on something that in the Real World often gets enough chapters to make its own book.

Until then, read perlipc and perlfork, Chapter 16 of the Camel, and the chapter(s) on signal handling in the nearest System Programming for Unix book. I'm going to go through them again (it's been awhile) and see if I can't grok in fullness.
