Subject: [PATCH] SICS-764: Provide access to the asynnet socket descriptor's
 write buffer. We need this to implement a "capture" command that doesn't
 cause SICS to commit suicide if you capture a "run" command. NOTE: This is a
 bit dodgy because we're trusting callers not to modify the write buffer.
