I want to let 32-bit software run under a 32-bit kernel.
This is what I did:
   - changed 'int' to 'short' in the message structs
   - changed catchsig.s crtso.s etc

It works well, but I think read() and write() are problematic since
read(fd,buf, 100000) will fail.

Am I correct that read and write are the only problematic calls?
file descriptors, m_type etc can safely be short.

If I am correct, it might be useful to have wrappers that divide a long
read request into shorter ones.
