Pls document relay with restricted socket count

There is documentation in the Tor manual about how to alleviate the problem of constrained socket memory (ConstrainedSockets, ConstrainedSockSize), but not about a restricted number of sockets.

The problem of a restricted number of TCP sockets is particularly acute in OpenVZ VPSs. A vendor may offer a great deal of bandwidth, but then restrict the practical use of it by imposing a low limit on the number of sockets in use.

So... how do I tell my relay to use no more than n TCP sockets?
