Description:
At <A HREF=http://dev.mysql.com/doc/refman/5.1/en/server-system-variables.html#sysvar_thread_handling>http://dev.mysql.com/doc/refman/5.1/en/server-system-variables.html#sysvar_thread_handling...> the valid values given are "no-threads" and "one-thread-per-connection".

The description mentions "one-thread", but not "no-threads".  However, "one-thread" doesn't appear in the list of valid values.

How to repeat:
Go to the web page above.

Note the following:

Version Introduced 	5.1.17
Command Line Format 	--thread_handling=name
Config File Format 	thread_handling
Option Sets Variable 	Yes, thread_handling
Variable Name 	thread_handling
Variable Scope 	Global
Dynamic Variable 	No
Value Set 	
Type 	enumeration
Valid Values 	no-threads, one-thread-per-connection

The thread-handling model. The allowable values are one-thread (the server uses one thread) and one-thread-per-connection (the server uses one thread to handle each client connection). one-thread is useful for debugging under Linux; see MySQL Internals: Porting. This variable was added in MySQL 5.1.17 

Suggested fix:
Valid values should be in the list and described....

Thank you for your bug report. This issue has been addressed in the documentation. The updated documentation will appear on our website shortly, and will be included in the next release of the relevant products.

one-thread in the description is incorrect, it should be no-threads.
