  You're right, I really need to write a javascript interpreter and
embbed it in libxml2 so we can rewrite all the upper layers.

Nah, dynamic languages suck even more.  Particularly interpreted ones.

  let ids =
    try List.map int_of_string (String.nsplit cpulist ",")
    with Failure "int_of_string" ->
      raise (VirshError (cpulist ": invalid format"))

That's the same code (actually better - not only does it do the check, but it converts the CPU numbers to a list of integers for you), safer, the same speed as the C code, and a factor of 10 shorter.
