284	Parallel build sometimes fails because generic/adt/list.o does not exist	Jakub Jermář		"This is what I did:

  1. built default ia32 mainline,822
  1. touched uspace/lib/c/generic/devmap.c so that it had newer modification time
  1. make -j 6

And this is what I got:

The above steps don't always lead to this bug, but I can reproduce this in quite a short time.
