When parallel tests are enabled, plasma-querytest can fail with:

    5/11 Test  #5: plasma-querytest ....................Subprocess aborted***Exception:   0.02 sec
    ********* Start testing of QueryTest *********
    Config: Using QtTest library 5.15.10, Qt 5.15.10 (arm64-little_endian-lp64 shared (dynamic) release build; by GCC 11.3.0), unknown unknown
    PASS   : QueryTest::initTestCase()
    QFATAL : QueryTest::installAndQuery() QThread: Destroyed while thread is still running
    FAIL!  : QueryTest::installAndQuery() Received a fatal error.
    Loc: [Unknown file(0)]
    Totals: 1 passed, 1 failed, 0 skipped, 0 blacklisted, 3ms
    ********* Finished testing of QueryTest *********

I'm able to consistently reproduce this on an aarch64-linux machine.
`guix build --cores=1' can also work around this.

[arguments]<#:parallel-tests?>: Disable.  Follows what Debian has done.
