Review Comment:
   Yeah I've been using that for a couple years, quite handy to avoid possible 
buffer overflows.
   
   I'm setting it to 0 because that is the default value and what we were doing 
before with the previous constructor as shown here 
https://github.com/apache/thrift/blob/v0.17.0/lib/java/src/main/java/org/apache/thrift/transport/TNonblockingServerSocket.java#L75
   
   The value eventually makes it's way to being set as the soTimeout() value on 
the socket which mean it's an infinite timeout, so basically no timeout. 
https://github.com/apache/thrift/blob/v0.17.0/lib/java/src/main/java/org/apache/thrift/transport/TNonblockingSocket.java#L114
   
   We could make this configurable but for now i was just keeping the existing 
behavior as that would be a new config option and should be a new Issue/PR i 
would think.
