It can produce too high values (up to 256ms), which can negatively affect tail latency. The value was chosen long time ago and now it's a good idea to reconsider it. 2. It does not have low bound, so on any iteration it can produce a very small value that will lead to unnecessary cpu consumption. 3. It does not increase low bound with the number of iterations. So if the SpinLock is actually somehow locked for a very prolonged time, a waiter can still wake periodically. Rework the logic to solve these problems. Add lower bound of 128us, no code should rely on absence of episodic delays in this range as they can occur everywhere. Lower upper bound to 4ms. A thread sleeping for 4ms does not consume significant cpu time (see below). Grow lower bound with the number of iterations. This is cpu consumption of a process doing usleep(x) in a loop (sampled with ps): 64us -> 4.0% 128us -> 2.7% 256us -> 3.5% 512us -> 2.8% 1024us -> 1.6% 2048us -> 0.6% 4096us -> 0.3% 8192us -> 0.0% Few millisecond sleeps do not consume significant time.

Abseil Team	87a4c07856	Export of internal Abseil changes. -- 8becce38c862a044db194a9aea1b505796a46d6f by Abseil Team <absl-team@google.com>: Updates the FixedArray's constructors to be exception safe by preventing double deletions. Also adds exception safety tests for FixedArray to document/enforce the expected behavior. PiperOrigin-RevId: 201964431 -- 794188b401a602b4be97190fb8738066fe1f9ca5 by Derek Mauro <dmauro@google.com>: Fixes for str_format.h documentation. PiperOrigin-RevId: 201951760 -- beae3bdd6eee2cf61101102fddc35ada188f330b by Alex Strelnikov <strel@google.com>: Add numeric_limits specialization for uint128. Turns out numeric_limits is a case where the consensus is that it is okay to specialize for a user defined type.

PiperOrigin-RevId: 201692176 -- bbfcaa7b1af331d9b97c92470608240c5c864fbc by Xiaoyi Zhang <zhangxy@google.com>: Use ABSL_HAVE_ANY/OPTIONAL/VARIANT to conditionally compile out the definition of absl::bad_any_cast, absl::bad_optional_access, absl::bad_variant_access. This would fix the issues where users #include those header directly in C++17 modes.
