The Solaris problem is that the stdio FILE structure only uses 8 bits 
to store the file descriptor.  However, these shell commands:

   LD_PRELOAD_32=/usr/lib/extendedFILE.so.1
   export LD_PRELOAD_32

preloads a module which updates the stdio implementation to use a 
different FILE member for the file descriptors, which is much larger.

Regardless, the same issue occurs with both the stdio-hack and 
without.  There are no other errors pertaining to file handles so I 
think that this issue must be specifically due to a bug in the log 
file re-opening code.
