What are the consequences of creating a new thread in the system?

Creating a new thread in the system involves several consequences:

• Resource usage: each thread requires allocation of system resources — memory for the stack, descriptors, etc.
• Scheduling overhead: the operating system must manage context switching between threads, which affects performance.
• Synchronization complexity: when working with shared resources, mechanisms like mutexes and semaphores are needed to avoid data races.
• Increased debugging difficulty: multithreaded programs are harder to test and debug due to unpredictable execution order.

Thus, creating a thread is not just about launching additional code, but also imposes significant load on the system and complicates the application's architecture.
