BUG#13987 Cluster: Loss of data nodes can cause high CPU usage from ndb_mgmd
A further reduction in CPU usage by ndb_mgmd with failed data nodes.
ndb/src/common/util/socket_io.cpp:
Use a nonblocking socket to peek at the buffer to know how much to read for socket_readln.
This saves us a lot of syscalls. By a lot, I've observed about halving the CPU
usage of ndb_mgmd with 1 failed node on a 6 node cluster.
