Dont spin main for queue (#443) 
* Use DynamicLatch in DispatchQueue to avoid main thread spinning

Replace the busy-yielding pending_task_count_ loop in DispatchQueue::finishTasks
with a blocking DynamicLatch. This avoids having the main thread consume CPU
cycles while waiting for dispatched tasks to complete.

The DynamicLatch implementation uses C++20 std::atomic::wait/notify_all for
efficient blocking and wakeup, with proper release-acquire semantics to ensure
task results are visible to the waiting thread.

* Reformat DynamicLatch to match DispatchQueue style

* Update attribution headers in DispatchQueue files to note modifications

Merge pull request #365 from hzeller/feature-20260525-keep-inc 
Explicitly mark dependencies as keep for bracket-headers used.
 2026-05-26 14:24:13 +00:00
Henner Zeller 224907d153 Explicitly mark dependencies as keep for bracket-headers used. 
This project uses bracket includes for dependencies that are
actually vendored via the MODULE.bazel.
So they should use `"zlib.h"`, `"tcl.h"` etc, but here they
use `<zlib.h>`, `<tcl.h>` which makes them look like system headers.

They are meant to be using the vendored headers, to explicitly tell
build_cleaner (`bant`) that the dependencies should be kept.
(ideally, we fix the includes, but since this is a fork, this might
be harder to maintain).

Also keeps `@openmp` for now, but see #364 if this is actually
needed.
