Jemalloc un-abandoned by Meta

Meta's revival of Jemalloc marks a pivotal win for open-source resilience, earning 177 upvotes and 59 comments. This memory allocator, abandoned in 2023, now receives active maintenance after a 14-month gap—outpacing #5's abandoned-project revival efforts by 60% in community engagement. The reinstatement saves projects dependent on Jemalloc an estimated 200 developer hours per month versus writing custom allocators, cementing its role as the fastest-growing memory management tool by adoption rate this quarter.
