fs/zfs/t_zpool/create test failure

[Andreas Gustafsson <gson%gson.org@localhost>]

Hi all,

The ATF tests are now almost passing on i386.  "Expected failures"
aside, only one test case is consistently failing in every run:
fs/zfs/t_zpool/create.  It started failing in June; the logs indicate
that it was broken either by the merge of the rmind-uvmplock branch on
CVS date 2011.06.12.03.35.36, or by one of the commits made during the
24-hour period of build breakage that began with that merge and ended
at 2011.06.13.04.30.40.

An example of test output with only this test failing is at

  
http://releng.NetBSD.org/b5reports/i386/build/2011.08.31.08.15.08/test.html#failed-tcs-summary

Anyone have an idea what is wrong here and how to fix it?
