 It helps both with mpd5.5 and mpd5.6.
 Now under network load top lines in `top' are

  PID USERNAME PRI NICE   SIZE    RES STATE    TIME   WCPU COMMAND
   10 root     155 ki31     0K     8K RUN      2:19 60.74% idle
   11 root     -72    -     0K   112K WAIT     1:47 32.03% intr{swi1: netisr 0}

And system is very responsive.

  ng_queue is not in top 17 (one screen) lines of `top' any more, it
 looks usual to me.

 I'll try to find revision, which breaks ULE + NetGraph by binary
search, but it takes some time as here is 590 revisions in "head/sys"
between previous version I used (which works Ok with ULE) and current
version (which doesn't). So, it should be ~9 iterations, and every
iteration takes ~1 hour and I could not spend 9 hours in row on this
task.
