Bug #8226 Cannot connect via shared memory

Description:
A simple setup for using memory as a way to connect to the server in Windows fails. See how to repeat:

How to repeat:
.
C:\mysql-4.1\my.ini
##### my.ini #####
[client]
protocol=memory
shared-memory-base-name=MySQL

[mysqld]
shared-memory
shared-memory-base-name=MySQL

2.
C:\mysql-4.1\bin\mysqld --install MySQL --defaults-file=C:\mysql-4.1\my.ini

3.
Running MySQL on Windows Service.

4.
C:\mysql-4.1\bin\mysql --defaults-file=C:\mysql-4.1\my.ini
---> ERROR 2038 (HY000): Can't open shared memory; client could not create request event (5)

At this point there is no way to connect to the server, so it can't be stopped with mysqladmin and must be killed with End Process in Task Manager.

Suggested fix:
None.

What is the server's output?
Was shared memory created successfully (if it wasn't, there must a warning in the log).
