Description:
When run on Solaris, the high concurrency test takes about an hour to close down user threads after the test has completed, when the standard 2000 user threads are run. This is about 5-10x higher longer than on Linux and much longer than with fewer threads. With 1500 user threads, the overhead was only 10 minutes. The concern is that with more that 2000 threads the overhead will become unreasonably high.

How to repeat:
Run the high concurrency test https://inside.mysql.com/wiki/SystemQATestPlan#High_Concurrency

You can edit high.tst to use a short value for DURATION, i.e. 10 minutes.
