描述

Certain workloads can create hundreds of thousands of fibers. Each fibers eats up a few KB of runtime memory. These workloads could be sporadic. Zombie fibers sit in the cache forever. Instead of forever, cache fibers for a limited amount of time, then destroy. Keep only-so-much cached fibers.

研究方向
Investigate the fiber lifecycle in Tarantool's source code, focusing on the zombie fiber cache mechanism. Look for relevant files such as 'fiber.c' or 'fiber.h' in the source tree. Consider adding a configuration option for maximum cache size and a timeout for cache eviction. Review the existing fiber implementation to understand how fibers are stored and destroyed.
