[plt-scheme] How many sockets can be open?

There are various OS limits on the total number of file descriptors,
and the file descriptors per process.  We document the issue on Linux


Sorry I can't help with the specifics for OS X, but I imagine the
situation is similar.  First thing to do is try the limit or ulimit
commands in your shell (command varies by shell).  If that doesn't
work hit Google to find the magic.
