The post discusses a technical problem encountered when the UI thread hangs due to a conflict during a kernel call. User comments indicate that this issue often arises from interactions between native memory allocation and managed runtimes' garbage collection (GC) processes. Notably, suspending threads in managed languages is sometimes unavoidable, particularly during GC, leading to potential deadlock scenarios when multiple runtimes are present. The proposed solution suggests implementing a hierarchy or mutual exclusion protocols for managing thread suspensions effectively to prevent these conflicts.
