… of live-instance cap `activeClientsSemaphore` already limits how many server instances can be alive at once (idle, leased, or booting), but placed no limit on how many `LoadSolution` boots -- process spawn + prebuild `dotnet build` callback + MSBuild solution load, the CPU/disk-heavy phase -- run concurrently. Profiling a local run showed CPU usage dropping to near-idle for long stretches between fixture-test bursts, suspected to be boot-phase contention (concurrent nested `dotnet build` calls racing MSBuild's own build node). Adds a second, independent throttle in `poolManager`'s own state: `InFlightBoots` tracks the actual `Task` for each in-flight boot (not just a count), admitting a new boot immediately if under `maxConcurrentBoots`, otherwise queuing it (FIFO) until a slot frees up. Scales with core count (one slot per 4 logical cores, floor, minimum 1) rather than a flat constant, so small CI runners (e.g. 4-vCPU GitHub Actions) get exactly 1 concurrent boot instead of racing several. 🤖 Generated with [ECA](https://eca.dev) (anthropic/claude-sonnet-5) Co-Authored-By: eca-agent <git@eca.dev>
