Since the kernel might remove the /proc/<pid>/task/<tid>/status at any time if the thread terminates, the code needs to handle possible fopen/getline/fclose failures due to an inexistent file.

The polling is used over ptrace to avoid the need to handle signals on the target pid and to handle some system specific limitation (such as YAMA). The polling has some limitations, such as resource consumption due the procfs read in a loop and the lack of synchronization after the state is obtained. The interface idea is to simplify some sleep synchronization waitid tests and is to reduce timeouts by replacing arbitrary waits.
