When you nohup a program, are all other processes that generated by that program also "nohup'd"?

(as in a perl program with fork/exec?)

Yes; after a fork, the new process inherits the same
signal handling masks as its parent. And luckily so,
because imagine what would happen if the following
shell script were issued:

   nohup sh foo

where foo contains a long pipeline of processes like:

   bar | baz | fred

kind regards,
