"This permits the behavior that occurs on Linux and many other "
"implementations, where, as with other errors that may be reported by "
"B<close>(), the file descriptor is guaranteed to be closed.  However, it "
"also permits another possibility: that the implementation returns an "
"B<EINTR> error and keeps the file descriptor open.  (According to its "
"documentation, HP-UX's B<close>()  does this.)  The caller must then once "
"more use B<close>()  to close the file descriptor, to avoid file descriptor "
"leaks.  This divergence in implementation behaviors provides a difficult "
"hurdle for portable applications, since on many implementations, B<close>()  "
"must not be called again after an B<EINTR> error, and on at least one, "
"B<close>()  must be called again.  There are plans to address this conundrum "
"for the next major release of the POSIX.1 standard."

"Dies erlaubt das Verhalten, das auf Linux und vielen anderen "
"Implementierungen auftritt, bei dem, wie auch bei anderen von B<close>() "
"berichteten Fehlern, garantiert wird, dass der Dateideskriptor geschlossen "
"ist. Es erlaubt allerdings auch eine andere Möglichkeit: dass die "
"Implementierung einen Fehler B<EINTR> zurückliefert und den Dateideskriptor "
"offen hält. (Laut seiner Beschreibung ist dies für B<close>() unter HP-UX "
"der Fall.) Der Aufrufende muss dann erneut B<close>() verwenden, um den "
"Dateideskriptor zu schließen und Lecks bei Dateideskriptoren zu vermeiden. "
"Diese Divergenz in Implementierungsverhalten stellt eine schwierige Hürde "
"für portable Anwendungen dar, da unter vielen Implementierungen B<close>() "
"nicht nach einem Fehler B<EINTR> erneut aufgerufen werden darf, und bei "
"mindestens einer B<close>() erneut aufgerufen werden muss. Es gibt "
"Überlegungen, dieses Puzzle für die nächste Hauptveröffentlichung des "
"Standards POSIX.1 zu lösen."

#.  One such race involves signals and ERESTARTSYS. If a file descriptor
#.  in use by a system call is closed and then reused by e.g. an
#.  independent open() in some unrelated thread, before the original system
#.  call has restarted after ERESTARTSYS, the original system call will
#.  later restart with the reused file descriptor. This is most likely a
#.  serious programming error.
