+/*****************************************************************
+ * ReadRequestFromClient
+ *    Returns one request in client->requestBuffer.  The request
+ *    length will be in client->req_len.  Return status is:
+ *
+ *    > 0  if  successful, specifies length in bytes of the request
+ *    = 0  if  entire request is not yet available
+ *    < 0  if  client should be terminated
+ *
+ *    The request returned must be contiguous so that it can be
+ *    cast in the dispatcher to the correct request type.  Because requests
+ *    are variable length, ReadRequestFromClient() must look at the first 4
+ *    or 8 bytes of a request to determine the length (the request length is
+ *    in the 3rd and 4th bytes of the request unless it is a Big Request
+ *    (see the Big Request Extension), in which case the 3rd and 4th bytes
+ *    are zero and the following 4 bytes are the request length.
+ *
+ *    Note: in order to make the server scheduler (WaitForSomething())
+ *    "fair", the ClientsWithInput mask is used.  This mask tells which
+ *    clients have FULL requests left in their buffers.  Clients with
+ *    partial requests require a read.  Basically, client buffers
+ *    are drained before select() is called again.  But, we can't keep
+ *    reading from a client that is sending buckets of data (or has
+ *    a partial request) because others clients need to be scheduled.
