It makes the attempted delivery of a message to a non-existent session
an error.
You may also want to set $session->option(default => 1) in your
sessions, to make the attempt to deliver a message to a non-existent
handler an error.

Either through Alias parameters for component constructors or by calling
$kernel->alias_set("alias") in _start.

It is possible, but it is not very "safe". If you do not clean up
session references properly, your program will leak memory (and probably
other things).
It's better to pass around $session->ID instead. These are like weak
session references. You can use them as destinations for post() and
other things.

You are saying that the Program is the return value of the function
POE::Component::Leve::leveShell::runShell(). Really you want it to be a
reference to the function:
Program => \&runShell,
Program => \&POE::Component::Leve::leveShell::runShell,

The child program is not run like the rest of POE. It is called only
once, with the parameters given in POE::Wheel::Run's ProgramArgs, and
the child process will exit when it returns.
