Delay re-queued callbacks a bit.

Walkthrough

The callback processing logic in psyqo::Kernel::Internal::pumpCallbacks() was updated. Instead of looping until the callback queue is empty, the function now processes only the callbacks present at the start by capturing the queue size and iterating that many times. No changes were made to public interfaces.

Changes

File(s)	Change Summary
src/mips/psyqo/src/kernel.cpp	Updated callback processing loop to iterate over initial queue size.

Poem

In the kernel’s queue, callbacks once spun,
Now counted up front, each one gets done.
A hop, a skip, with logic anew,
The rabbit keeps order, as callbacks queue.
With a loop so precise, the work’s never through! 🐇

412-413: Excellent architectural improvement for callback processing.

This change transforms the callback pumping from potentially unbounded processing to a predictable, bounded operation. By capturing the initial queue size and processing only that many callbacks, you've effectively:

1. Prevented infinite loops - Callbacks that re-queue themselves or others won't cause endless processing
2. Ensured bounded execution time - Critical for real-time systems like game engines
3. Maintained FIFO ordering - Callbacks are still processed in the correct order
4. Introduced controlled latency - Re-queued callbacks are delayed to the next pump cycle, which aligns with the PR title

The implementation is thread-safe and correct - the size is captured within the critical section ensuring consistency.
