Update `JuliaExecutor.run()` to use pool - -3. Add pool cleanup on shutdown - -**Expected speedup:** 50-100x for repeated executions - -**Trade-offs:** -- ✅ Massive speedup -- ✅ Lower CPU overhead -- ⚠️ More memory (keeps processes in RAM) -- ⚠️ Needs careful state management - ---- - -### 4.

Julia REPL Worker (`julia_repl_worker.jl`) -A persistent Julia process that: -- Runs as a REPL accepting code via stdin -- Executes code and captures output using pipes -- Communicates using a delimiter-based protocol -- Handles errors gracefully and recovers - -### 2. Julia Process Pool (`julia_process_pool.py`) -Python class that: -- Manages multiple persistent Julia worker processes -- Provides thread-safe process allocation -- Handles automatic recovery from failures -- Ensures proper cleanup on shutdown - -### 3.
