When you call close() on a file, it will be flushed and closed
immediately. From what you described, it seems more likely to me that
the FPC code is probably opening and reading the file before the LISP
code has finished writing it (and/or vice versa), because FPC's
standard I/O routines do not try to acquire exclusive access files
(regardless of whether you open them for reading and/or writing).
The Carbon routines probably do check for exclusive access by default,
so the LISP code will only open the file once the MW/FPC code is
finished, and vice versa.
