fix(profiling): release the GIL for internal mutation

P403n1x87 · P403n1x87 · commit ae5f97368cb6 · 2025-10-13T15:05:54.000+01:00
We make the stack v2 sampler release the GIL when performing internal
state mutation that can require acquiring other internal locks. This
gives the chance to other threads to make progress while the tracking
operations wait on an internal mutex.
