Yup, your operating-system is lying to you (well, to the LDM program).
The file /usr/include/sys/syslimits.h defines OPEN_MAX to be 10240.
According to the UNIX standard, if this macro is defined, then it's
the maximum number of open file descriptors that a program can have.
The system call "sysconf(_SC_OPEN_MAX)", however, returns 256 on 
your system, which is probably the correct number.  The UNIX standard
says that this system call should only be used, however, if OPEN_MAX
is *not* defined.  Sigh.

I'll see about modifying the LDM program to accommodate this flaw in
Darwin.  In the meantime, keep using the "-close" option.

Regards,
Steve Emmerson
