Description:
Shared memory connections do not work in the latest 4.1 and 5.0 releases.

How to repeat:
Either add shared-memory to  the appropriate my.ini file or add it to the comman d line
and start the server.  

Connect to the server using mysql -u root (it will use shared memory by default)

Issue status command.  The output stalls and mysql hangs.
It can be hung with other commands too.

It hangs with show variables command also.

this happens because we don't support non-blocking reads on shared memory, but the code
isn't quite set up right to deal with that.
