Today (Saturday) We will make some minor tuning adjustments to MySQL.

You may experience 2 up to 10 seconds "glitch time" when we restart MySQL. We expect to make these adjustments around 1AM Eastern Daylight Saving Time (EDT) US.

PTHREAD_KILL_OTHER_THREADS_NP(3)			     Library Functions Manual				  PTHREAD_KILL_OTHER_THREADS_NP(3)

NAME
pthread_kill_other_threads_np - terminate all threads in program except calling thread
SYNOPSIS
#include <pthread.h> void pthread_kill_other_threads_np(void);
DESCRIPTION
pthread_kill_other_threads_np is a non-portable LinuxThreads extension. It causes all threads in the program to terminate immediately, except the calling thread which proceeds normally. It is intended to be called just before a thread calls one of the exec functions, e.g. execve(2). Termination of the other threads is not performed through pthread_cancel(3) and completely bypasses the cancellation mechanism. Hence, the current settings for cancellation state and cancellation type are ignored, and the cleanup handlers are not executed in the terminated threads.

BUGS
According to POSIX 1003.1c, a successful exec* in one of the threads should terminate automatically all other threads in the program. This behavior is not yet implemented in LinuxThreads. Calling pthread_kill_other_threads_np before exec* achieves much of the same behavior, except that if exec* ultimately fails, then all other threads are already killed.
