I cannot figure out when the reply was sent back because there is a
lot of chatter on the system dbus, but I definitely see the pause
after the following message was sent

1289374216.174405 sendmsg(23, {msg_name(0)=NULL,
msg_iov(2)=[{"l\2\1\1I\32\0\0\305\261\5\0-\0\0\0\6\1s\0\5\0\0\0:1.61\0\0\0\5\1u\0\32\0\0\0\10\1g\0\1s\0\0\7\1s\0\4\0\0\0:1.7\0\0\0\0",

The next recvmsg for that same file descriptor (23) happens 25 secs
later and it seems to be the response to the interospection because
there is a bunch of data coming down the pipe line (
