I think it should be noted that "sleep" only functions on integer time increments...

Unless you use Time::HiRes...

Perhaps I need to rephrase my original question:

What's the proper way to set SO_LINGER ? Ancient memories of Unix and TLI lead me to believe I need 2 values: a flag to enable, and another value to set the timeout. Based on the perl examples I've surfaced thus far, approx. 50% are doing it the wrong way..
