Strange test failures

[Paul Goyette <paul%whooppee.com@localhost>]

After finally resolving several build breaks as well as the breakage due 
to ksem module being unload, there is still something very broken in 
NetBSD-current.  I'm suspecting some breakage in the file system code, 
but I really don't have a clue on how to further isolate the problem(s).

First of all, a large number of tests that were previously working are 
now failing:

Failed test cases:
    fs/nfs/t_rquotad:get_nfs_be_1_both,
    fs/nfs/t_rquotad:get_nfs_be_1_group,
    fs/nfs/t_rquotad:get_nfs_be_1_user, fs/nfs/t_rquotad:get_nfs_le_1_both,
    fs/nfs/t_rquotad:get_nfs_le_1_group,
    fs/nfs/t_rquotad:get_nfs_le_1_user, fs/vfs/t_renamerace:lfs_renamerace,
    lib/libc/stdlib/t_strtod:strtod_inf, lib/libevent/t_event:kqueue,
    lib/libevent/t_event:poll, lib/libm/t_infinity:infinity_long_double,
    lib/librumpclient/t_fd:sigio, lib/librumphijack/t_sh:redirect,
    lib/librumphijack/t_sh:runscript, lib/librumphijack/t_tcpip:http,
    lib/librumphijack/t_tcpip:nfs, lib/librumphijack/t_tcpip:ssh,
    lib/librumphijack/t_vfs:cpcopy, lib/librumphijack/t_vfs:mv_x,
    lib/librumphijack/t_vfs:paxcopy, lib/semaphore/pthread/t_sem_pth:named,
    syscall/t_getrusage:getrusage_utime_back,
    syscall/t_getrusage:getrusage_utime_zero

The nfs/t_rquotad test failures are semi-expected time-outs, although it 
is unusual for all six test cases to fail in a single pass.  Similarly, 
the libevent/t_event failures are fairly common failures.

But the lib/librumpclient failures have previously passed successfully, 
so this is quite unexpected.

In addition, when running the atf tests via "anita interact" with the
command

        atf-run | tee /tmp/X | atf-report -o ticker:- -o xml:/tmp/Y

(which is essentially the same command that "anita test" uses), we get 
some strange interweaving of output.  Note in the below example that 
output from a previous execution of t_grow_swapped (test #348) is 
displayed it the middle of the output from the current execution of 
tests t_mkdir (test #106)!

fs/tmpfs/t_mkdir (106/399): 5 test cases
