zombie question

[Blair Lowe]

Hi,

Please also be aware that BSD and SYSV UNIX deal with zombies 
differently. It has to do with the sleeping properties of the parent.

You will need a switch to determine the operating system type, and 
deal with the processes differently depending on what it is.

Also, does conn.close cut off the child from the calling parent? Just 
a dumb guess.

Blair.
