Getting kerberos to use fds > 256

[Nicolas Williams]

This is the Solaris 32-bit stdio is limited to 256 file descriptors.

A typical solution that works is to dup2() new fildes up above 256 for
fildes that need not be used with stdio, thus reserving the first 256
fildes for things that need stdio. This is a very app-specific hack, but
it can be generalized into an LD_PRELOADable library that more generally
solves the problem(*).

Another typical solution is to use the 64-bit Solaris environment.

(*) This is left as an exercise for the reader.
