/*
The current implementation of std::call_once has a bug described in
https://stackoverflow.com/questions/41717579/stdcall-once-hangs-on-second-call-after-callable-threw-on-first-call.
This is likely caused by a deeper bug of pthread_once, which is discussed in
https://patchwork.ozlabs.org/patch/482350/
This wrap is a hack to avoid this bug.
