Yes it is correct

It can be used to run perl with some flags like perl -W or perl -MCPAN 
personally i use it for debuging purposes.

Yes

If your perl is threaded then you will need to use subroutine called CLONE in 
which you can define local variables per thread. This subroutine is called 
automatically from perl when new clone is created. You can put for example 
database connections in this sub (sorry no example in example.pl) In this 
case it will be better to use fixed size pool of perl clones (this is to 
avoid destroy and reconnect to DB)

      max_clones = 32
      start_clones = 32
      min_spare_clones = 0
      max_spare_clones = 32
      cleanup_delay = 5
      max_request_per_clone = 0
