from the OS X man page: (freebsd is same)
wchan The event (an address in the system) on which a process waits.
When printed numerically, the initial part of the address is
trimmed off and the result is printed in hex, for example,
0x80324000 prints as 324000.

Yes lots of "pages" but I wouldn't call it "info".
What does 'select' mean? What about unix_stream_data_wait, wait4, read_chan, nanosleep. That is what is the process waiting on. Selecting what? polling what?
unix_stream_data_wait? Where can I learn about which data stream it is waiting on? Will lsof tell me? (I guess I can look there.)
