    Description

      Related to MB-45010, where we have a crash during a collection rebalance test (under Magma). Due to GCC Bug 55917 which is present in the version of GCC we use, we don't have an accurate backtrace of where the crash was from.

      To allow us to triage MB-45010 (determine if it affects only Magma or also couchstore), we need to workaround the aforementioned GCC bug - most straightforward option would be to avoid std::thread when creating threads for FollyExecutorPool.
