Warning about network connections
This may be obvious, but I thought I'd point out that if you suspend (kill -STOP) a process that has an active network connection, the connection will almost certainly be dropped if you leave it stopped for any length of time. Like I said, this is only if it is something that keeps a connection open. An email program or web browser can be stopped since it only opens connections when it is checking mail or loading a web site, but a chat client or file transfer program will get disconnected if you suspend it. The actual length of time you can have it suspended depends on the protocol used... a general guideline is probably between 30 seconds and two minutes but that can vary widely.
Warning about network connections
I have found that it is possible to suspend downloads with wget for long periods and still be able to resume them, even if I have terminated and reconnected my internet connection. I have only used ctrl-z to suspend it (I am not sure if this differs from kill -STOP). Sometimes it takes a while to get going again, and sometimes it never does.

... wget reconnects.... that is very different from normal programs... |
