Temporary list of known bugs:
- MDTM and SIZE will fail if the user hasn't got read access to the file. (Is
  this considered a bug?)
- The server will not check for bad file descriptors, and will enter an
  infinite, CPU-hogging loop when something goes wrong with a connection (and
  libc fails to notify us). (The connection will time out after 15 minutes,
  though, and it's a long time since I've seen this bug anyway.)
- The server always sends data in 1460 bytes chunks (due to the default MTU
  on Ethernet interfaces). This is wrong on many links. (Hopefully the TCP/IP
  stack will fix this for now.)
- The server is still known to segfault from time to time, but unfortunately,
  most kernel versions won't dump core if the program has changed uid :-(
- Sometimes (after an error) the server doesn't respond to the connection
  anymore. Weird.
- IE sends some weird characters (Telnet break?) before ABOR, we aren't
  ignoring them properly yet.
- Some commands are still not implemeted.
- BetaFTPD must defititely be run by root. Changing this is planned, but
  it will need a database-like system. If you need non-root support, you
  could for instance use FTP4ALL.
- There are no real dependencies in the Makefile.
