+Wait until one or more file descriptors are ready for some kind of I/O.\n\
+The first three arguments are lists of file descriptors to be waited for:\n\
+rlist -- wait until ready for reading\n\
+wlist -- wait until ready for writing\n\
+xlist -- wait for an ``exceptional condition''\n\
+If only one kind of condition is required, pass [] for the other lists.\n\
+A file descriptor is either a socket or file object, or a small integer\n\
+gotten from a fileno() method call on one of those.\n\
+\n\
+The optional 4th argument specifies a timeout in seconds; it may be\n\
+a floating point number to specify fractions of seconds.  If it is absent\n\
+or None, the call will never time out.\n\
+\n\
+The return value is a tuple of three lists corresponding to the first three\n\
+arguments; each contains the subset of the corresponding file descriptors\n\
+that are ready.\n\
