[M108 Aura Migration] Fix crash with memory sanitizer

With memory sanitizer or some utility, there can be another thread,
which is created for their purpose.

i.e.)
With VD duma, libduma makes an agent thread as static variable
before ZygoteMain() is called.

  efl_webprocess(5483)---{duma_comm}(5497)
