I'm really not sure about this example.  I assume you mean Perl 5.
Last I checked, Perl didn't really operate the way Rob suggests.
There is a "patch pumpking", but he is more analogous to Linus than
to Alan.  In particular, Larry Wall does not review the pumpking's
work at all (he instead sets general direction and makes key design
decisions).  If Perl doesn't have the problems observed in Linux, I
think it is because 1) Perl is smaller, 2) Perl 5 is largely in
bug-fix mode, 3) Perl has a culture of accepting patches with less
scrutiny (without meaning this as a slam, I think you can see
evidence of this in the Perl 5 source base).

There is an upper bound to the size of the delta one person can
maintain (well, assuming his goal is to sync those changes with
Linus).  Unless Linus's throughput increases dramatically, the
integrator's delta will grow until it reaches that bound.  At that
point, the integrator has to drop patches (or give up!).  How do you
get around this?
