Proc::Fork

This module provides an intuitive, Perl-ish way to write forking
programs by letting you use blocks to illustrate which code section
executes in which fork. The code for the parent, child, retry handler
and error handler are grouped together in a "fork block". The clauses
may appear in any order, but they must be consecutive (without any other
statements in between).

All four clauses need not be specified. If the retry clause is omitted,
only one fork will be attempted. If the error clause is omitted the
program will die with a simple message if it can't retry. If the parent
or child clause is omitted, the respective (parent or child) process
will start execution after the final clause. So if one or the other only
has to do some simple action, you need only specify that one. For
example:

 # spawn off a child process to do some simple processing
 run_fork { child {
     exec '/bin/ls', '-l';
     die "Couldn't exec ls: $!\n";
 } };
 # Parent will continue execution from here
 # ...

If the code in any of the clauses does not die or exit, it will continue
execution after the fork block.
