Morten,
I think in select.c is a bug:
If I figure out the code correctly, it goes like this: 

  - Check all fds from 0 to fdmax if they are ready, etc
  - After that, check via the __file_rec all descriptors that
    claim to be not ready.

The first step handles File System Extension correctly, the second
goes wrong for FSEs that got a fd from __FSEXT_alloc_fd. They
are connected to DOS's nul device, which is always ready. So, even if 
a FSE says the file is not ready, the second test will overrule its 
answer.

CIao
