Description:
according to
http://dev.mysql.com/doc/refman/6.0/en/server-system-variables.html#option_mysqld_thread_h...

you have to build your own binaries to use this.  why?

E:\mysql-6.0.5-alpha-winx64\bin>mysqld  --console --thread_handling=pool-of-threads
Unknown option to thread_handling: pool-of-threads
Alternatives are: 'one-thread-per-connection','no-threads'

080729 20:01:19 mysqld_safe Starting mysqld daemon with databases from
/home/sbester/mysql/6.0/mysql-6.0.4-alpha-linux-i686-glibc23/data
Unknown option to thread_handling: pool-of-threads
Alternatives are: 'one-thread-per-connection','no-threads'

How to repeat:
download some version of >=6.0.4 from http://dev.mysql.com/downloads/mysql/6.0.html and
install it, then run: mysqld  --console --thread_handling=pool-of-threads

Suggested fix:
i suggest binaries are built with the feature enabled so that majority of users will
actually test it

setting as verified, as we need more community testing on this.

This option should be enabled on platforms that support it: Linux, Solaris, Mac OS X.

In 6.0.8 all Linux, Mac OS X and Solaris binaries have
pool-of-threads support.

andling

The manual does not say that. It says only that MySQL must be configured with
--with-libevent. It is neutral on the question of whether binary builds are configured
that way.

Noted in 6.0.8 changelog.

Binary distributions for Solaris, Linux, and Mac OS X now are built
with support for the pool-of-threads value of thread_handling.

Linux RPMs still don't have the "--with-libevent" option needed

As of 6.0.10 the following platforms are still missing libevent support, in addition to
RPMs:

aix5.2-powerpc-32bit
aix5.2-powerpc-64bit
aix5.3-powerpc-32bit
aix5.3-powerpc-64bit
freebsd6.3-x86
freebsd6.3-x86_64
freebsd7.0-x86
freebsd7.0-x86_64
hpux11.11-hppa-32bit
hpux11.11-hppa-64bit
hpux11.23-ia64
i5os-power-32bit
i5os-power-64bit

I will verify these to see whether they can be enabled, but I have a feeling this is only
likely to be the case for FreeBSD, and enable them as well as RPMs for the 6.0.11 build.

6.0.11 was built with libevent on all platforms except Windows.

For the record, Windows does in fact include libevent.
