+Being careful with signals

+	The library uses signals internally. The signal handler is
+	registered with the SA_RESTART flag. However, these signals may cause

+	should be taken to restart system calls manually if they fail with this
+	error. A list of non-restartable system calls may be found in
+	signal(7).
