Correct me if I'm wrong, but I think that it's more a bug in the NFS protocol 
than in the Linux (or Solaris, etc) NFS implementation.  The problem is that 
NFS itself just doesn't pass that information along.  The NFS server has no 
idea that the 'text' file is being executed, so it doesn't know that it 
should "return" ETXTBSY.

Now, this might be different in NFS v3, but I'm pretty sure that this applies 
for v2, at least.
