Module startup_guard 

Structs

StartupLockGuard

Functions

crash_loop_backoff

Detects rapid restart loops (e.g., IDE keeps respawning a crashing MCP server). Records each startup timestamp; if too many happen within the window, sleeps with exponential backoff to break the loop and avoid host degradation.

try_acquire_lock

Best-effort cross-process lock (create_new + stale eviction).
