What sort of locks does a Streaming ResultSet produce?

I ran some simple tests with streaming resultsets to find out, what kinds of locks I would get (according to the manual all tables used in a streaming resultset will be locked).

I wrote a simple test case that opens a connection and executes a SELECT * FROM table statement with the streaming mode flags set.
While that statement was running (I put a delay in the loop getting all the rows) I tried to select and insert from and into that same table without any problems, both from a command line and another Java client.

I am using InnoDb tables. Could someone enlighten me, what kinds of locks are to be expected and in what situations?
