// Phase 2: on-demand (NON-warm) pthread Worker creation WITHOUT modifying KiCad.

|

|
|
// The real KiCad pool (compiled-in kicad/common/thread_pool.cpp, via GetKiCadThreadPool())
|
||
|
|
// consumes ALL the pre-warmed Workers at construction; raw fly-threads beyond that count
|
||
|
|
// must then be created ON DEMAND, whose 'loaded'->'run' handshake needs the main event loop.
|
||
|
|
// The fix is wasm/shims/nanosleep_yield.c (a strong nanosleep override): the main-thread sleep_for
|
||
|
|
// join Asyncify-yields so the loop services the handshake and the on-demand Workers boot.

// Named coroutine-* so playwright-coroutine.config.ts runs it in real Chrome + Firefox.

// WebKit is skipped for pthread apps (COEP worker-load limitation; doc 10 §2a).
