> From trunk TSAN build: the snprintf to a static buf in SaslGetOption is racy,

> synchronization:
> #2 kudu::rpc::SaslGetOption(void*, char const*, char const*, char
> const**, unsigned int*) /home/todd/git/kudu/src/rpc/sasl_common.cc:90
> (libkrpc.so+0x0000000c02a8)
> #3 sasl_client_plugin_info <null>:0 (libsasl2.so.2+0x00000000866c)
> #4 kudu::rpc::Connection::InitSaslServer()
> /home/todd/git/kudu/src/rpc/connection.cc:525 (libkrpc.so+0x00000009649e)
