Fixes JuliaLang#54439. - Lock around concurrent accesses to .logs and .message_limits - Copy the vector out of the logger at the end, to shield against dangling Tasks. Before: ```julia julia> Threads.nthreads() 8 julia> function foo(n) @info "Doing foo with n=$n" @sync for i=1:n Threads.@Spawn @info "Iteration $i" end 42 end foo (generic function with 1 method) julia> for _ in 1:1000 @test_logs (:info,"Doing foo with n=10000") match_mode=:any foo(10_000) end julia+RAI(56155,0x1f5157ac0) malloc: double free for ptr 0x128248000 julia+RAI(56155,0x1f5157ac0) malloc: *** set a breakpoint in malloc_error_break to debug [56155] signal (6): Abort trap: 6 in expression starting at REPL[8]:1 signal (6) thread (1) __pthread_kill at /usr/lib/system/libsystem_kernel.dylib (unknown line) Allocations: 54370881 (Pool: 54363911; Big: 6970); GC: 119 [1] 56154 abort julia -tauto ``` After: ```julia julia> Threads.nthreads() 8 julia> function foo(n) @info "Doing foo with n=$n" @sync for i=1:n Threads.@Spawn @info "Iteration $i" end 42 end foo (generic function with 1 method) julia> for _ in 1:1000 @test_logs (:info,"Doing foo with n=10000") match_mode=:any foo(10_000) end ``` (no crash) :)
