Abstract
Provided are techniques for an OS to be modified on a running system such that running programs, including system services, so not have to be stopped and restarted for the modification to take effect. The techniques include detecting, by a processing thread, when the processing thread has entered a shared library; in response to the detecting, setting a thread flag corresponding to the thread in an operating system (OS); detecting an OS flag, set by the OS, indicating that the OS is updating the shared library; in response to detecting the OS flag, suspending processing by the processing thread and transferring control from the thread to the OS; resuming processing by the processing thread in response to detecting that the OS has completed the updating; and executing the shared library in response to the resuming.
