+=head2 NAMED LIMITER (PSGI)
+
+Named limiters are useful for preventing large inboxes from
+monopolizing (or overloading) the server.  Since serving git
+clones (via L<git-http-backend(1)> can be memory-intensive for
+large inboxes, it makes sense to put large inboxes on a named
+limiter with a low max value; while smaller inboxes can use
+the default limiter.
+
+C<RLIMIT_*> keys may be set to enforce resource limits for
+a particular limiter.
+
+Default named-limiters are prefixed with "-".  Currently,
+the "-cgit" named limiter is reserved for instances spawning
+cgit via C<publicinbox.cgitrc>
+
+=over 8
+
+=item publicinboxlimiter.<name>.max
+
+The maximum number of parallel processes for the given limiter.
+
+=item publicinboxlimiter.<name>.rlimitCore
+
+=item publicinboxlimiter.<name>.rlimitCPU
+
+=item publicinboxlimiter.<name>.rlimitData
+
+The maximum core size, CPU time, or data size processes run with the
+given limiter will use.  This may be comma-separated to distinguish
+soft and hard limits.  The word "INFINITY" is accepted as the
+RLIM_INFINITY constant (if supported by your OS).
+
+See L<setrlimit(2)> for more info on the behavior of RLIMIT_CORE,
+RLIMIT_CPU, and RLIMIT_DATA for you operating system.

+=head3 EXAMPLE WITH NAMED LIMITERS
+
+	; big inboxes which require lots of memory to clone:
+	[publicinbox "big1"]
+		mainrepo = /path/to/big1
+		address = big1@example.com
+		httpbackendmax = big
+	[publicinbox "big2"]
+		mainrepo = /path/to/big2
+		address = big2@example.com
+		httpbackendmax = big
+
+	; tiny inboxes which are easily cloned:
+	[publicinbox "tiny1"]
+		mainrepo = /path/to/tiny1
+		address = tiny1@example.com
+	[publicinbox "tiny2"]
+		mainrepo = /path/to/tiny2
+		address = tiny2@example.com
+
+	[publicinboxlimiter "big"]
+		max = 4
+
+In the above example, the "big1" and "big2" are limited to four
+parallel L<git-http-backend(1)> processes between them.
+
+However, "tiny1" and "tiny2" will share the default limiter
+which means there can be 32 L<git-http-backend(1)> processes
+between them.
