After a few investigation, the problem appears to be that the nucleus
assume that user-space skins will issue a bind syscall before using a
skin, and that the user-space RTDM library does not exit if binding
fails. So, there are two ways we can fix this problem:
- either we make the nucleus paranoid and have it handle gracefully
  syscalls to non loaded tables;
- or we make the user-space RTDM library behave like other skins and
  exit if the interface is not bound.
