Abseil (seems to be Google's equivalent of Folly) has an async-signal-safe spin lock. That might be easier than a doubly linked list. However, it doesn't seem to be easily vendored (just based on the fact that it has 10 abseil includes) :( https://github.com/abseil/abseil-cpp/blob/master/absl/base/internal/spinlock.h I'd agree that it seems too unlikely to worry about. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
