Description
目前各分支上仍存在一些手动drop，其中有些是不必要的，与调度相关的必要的drop也可以通过类似于ch9分支上的exclusive_session接口来规避。无需手动drop是Rust相比C语言的一大优势，要考虑或借鉴一种更好的设计达成这一目标。

Research direction
Review the manual drop sites across the branches and compare the scheduling-related cases with the exclusive_session interface on the ch9 branch. Determine which drops are unnecessary and whether that interface supports a better design. Done means reducing or avoiding manual drops without changing the intended scheduling behavior, but the issue names no specific files or tests.
