Colin Patrick McCabe commented on HDFS-7012:
--------------------------------------------

Shouldn't disableSigPipe be a private function, since it's called internally 
and doesn't need to be called externally?

{code}
+int32_t BufferedSocketReaderImpl::readVarint32(int timeout) {
+    int32_t value;
+    bool rc = false;
+    int deadline = timeout;
+    memmove(&buffer[0], &buffer[cursor], size - cursor);
{code}

Is there a way to avoid doing all this copying?
