Log message:
Don't ffree the newly allocated file before calling dupfdopen.
In some cases that could cause dupfdopen->fd_getfile to access freed memory
setting fd_ofiles[fd] to NULL is not a solution because that would cause
a race condition.

Free the new file after dupfdopen and use closef (because it will be necessary
in the future.

XXX - consider more cleanup of the code around dupfdopen.
