I've been playing with running hunchentoot under heavy loads using easy-acceptor,

and running against apache-bench (ab)

I noticed that logging to *error-output* often causes socket failures under heavy

load, at least in SLIME. Is there a reason why with-open-file-or-console in log.lisp

couldn't use a NIL pathname to simply not log, and pathname=T would log

to *error-output*, which is what NIL presently means? Now, there seems to be no

way to turn off logging (besides subclassing acceptor).

2. Backlog in listener:

I found that in the start-listening method in acceptor.lisp, there is no BACKLOG

set for usocket:socket-listen. I think that others have pointed this out as well.

The default apache backlog seems to be 100 to 512

[1,2,3] though the default on a macintosh seems silently limited to 128 [4]. In the usocket

routines used by hunchentoot backlog seems to be only 5. This seems

two orders of magnitude smaller than what is standard for web servers.

I tried putting in :BACKLOG 50 into the start-listening method in acceptor.lisp

and it eliminated most failures of ab. Is there any reason why acceptor objects

shouldn't have a new backlog slot default value in them much larger than 5,

which should be used in the start-listening method?

The appended patches implement both changes, if these suggestions are judged useful.

The backlog is 50. I hope they're done correctly; I'm not experienced in submitting patches.
