Description:
In ./mysqld --verbose --help,

--thread_handling only documents 2 options, even when the server is compiled
with pool of threads :

(begin quote)
--thread_handling=name
  Define threads usage for handling queries:
  one-thread-per-connection or no-threads
(end quote)

A third option exists but is not described.

How to repeat:
See the code in mysqld.cc

Supported options:

static const char *thread_handling_names[]=
{ "one-thread-per-connection", "no-threads",
#if HAVE_POOL_OF_THREADS == 1
  "pool-of-threads",
#endif
  NullS};

Documented options:

  {"thread_handling", OPT_THREAD_HANDLING,
   "Define threads usage for handling queries:  "
   "one-thread-per-connection or no-threads", 0, 0,
   0, GET_STR, REQUIRED_ARG, 0, 0, 0, 0, 0, 0},

Thank you for the report.

Verified as described.

Also there is no way to say configure to compile MySQL with pool-of-threads support.

Fixed in 5.5.13.
