!    AIX needs a workaround for I/O cancellation, see:

!    ...
!    The close subroutine is blocked until all subroutines which use the file
!    descriptor return to usr space. For example, when a thread is calling close
!    and another thread is calling select with the same file descriptor, the
!    close subroutine does not return until the select call returns.
