To ensure that the garbage collector is not running at the same time as Nasal execution, you could use a single condition variable to coordinate between the two threads. This condition variable could be used to signal when it is safe to run the garbage collector, and to prevent the garbage collector from running while Nasal code is being executed. By using a condition variable in this way, you can effectively coordinate between the two threads and ensure that the garbage collector is not impacting the program's overall performance. | To ensure that the garbage collector is not running at the same time as Nasal execution, you could use a single condition variable to coordinate between the two threads.

there is still the issue of not being able to execute Nasal code while the garbage collector is running. In order to fully address this issue, you would need to implement a concurrent garbage collector, which is a type of garbage collector that can run concurrently with the program and perform garbage collection without stopping the program's execution. | |||
A concurrent garbage collector is typically more complex to implement than a traditional mark/sweep garbage collector, as it needs to be designed in a way that allows it to run concurrently with the program without interfering with the program's execution. This can involve using sophisticated synchronization mechanisms, such as atomic operations and lock-free data structures, to coordinate between the garbage collector and the program. | |||
In the case of FlightGear, implementing a concurrent garbage collector would likely be a significant undertaking and would require a deep understanding of the program's internal workings and how it interacts with Nasal code. It would also require careful design and testing to ensure that the garbage collector does not interfere with the program's execution or cause any performance issues. | |||
Therefore, while running the garbage collector in a separate thread can improve its performance and reduce its impact on the program, it may not completely eliminate the issue of not being able to execute Nasal code while the garbage collector is running. In order to fully address this issue, a concurrent garbage collector would need to be implemented. | |||
