Dear Maintainer,

node-liftoff's testsuite appears to use method timing/benchmarking
in such a way that it will non-deterministically FTBFS:

  […]

  
    1) Liftoff launch should skip respawning if process.argv has no values from v8flags in it:
       Error: timeout of 5000ms exceeded
        at null.<anonymous> (/usr/lib/nodejs/mocha/lib/runnable.js:139:19)
        at Timer.listOnTimeout (timers.js:92:15)
  
  
  
  debian/rules:13: recipe for target 'override_dh_auto_test' failed
  make[1]: *** [override_dh_auto_test] Error 1
  make[1]: Leaving directory '«BUILDDIR»'
  debian/rules:8: recipe for target 'build' failed
  make: *** [build] Error 2
  dpkg-buildpackage: error: debian/rules build gave error exit status 2

  […]

The full build log is attached.


Regards,
