How to change priority of specific thread (lwt) in linux?

@raphaelle 

To change the priority of a specific thread in Linux, you can use the chrt command. Here's the process to follow:

1. Determine the PID (Process ID) of the thread you want to change the priority for. You can use tools like ps or top to find the PID. For example, let's assume the PID is 1234.
2. Use the chrt command with the desired priority to change the thread's priority. The command syntax is as follows: chrt -p
3. Verify that the priority has been changed successfully. You can use the ps or top command with appropriate options to check the priority of the thread.

Keep in mind that changing thread priorities may require root or administrative privileges. Additionally, changing priorities without proper understanding and consideration may result in adverse system behavior.
