History
Ian Lepore e1334f935f Fix a descriptor leak in devd. Clients reading /var/run/devd.pipe can close 
their socket connection any time, and devd only notices that when it gets an
error trying to write an event to the client.  On a system with no device
change activity, clients could connect and disappear repeatedly without devd
noticing, leading to an ever-growing list of open socket descriptors in devd.

Now devd uses poll(2) looking for POLLHUP on all existing clients every time
a new client connection is established, and also periodically (once a minute)
to proactively find zombie clients and reap the socket descriptors.  It also
now has a connection limit, configurable with a new -l <num> command line arg.
When the maximum number of connections is reached it stops accepting new
connections until some current clients drop off.
