Embedded Perl saves memory, since parts of the Perl interpreter can be
shared between the slaves, and it can let slaves initialize a bit
faster (since the parent process only has to initialize once),
although that should happen rarely enough that it's probably not too
noticeable.

David F. Skoll has reported that embedded Perl probably may not
actually help memory that much, since Perl's reference counting method
of garbage collection ends up touching almost every page of memory,
requiring each slave to have its own copy of the data anyway.
