A handful of aspects of our code require it and for anyone number of sections, we must produce our code in a very thread-Harmless way using locks, mutex or synchronization.

Atomic physics has proved to get a spectacularly prosperous application of quantum mechanics, which is amongst the cornerstones of modern physics.

But for UP (and possibly MP), If a timer interrupt (or IPI for SMP) fires Within this small window of LDREX and STREX, Exception handler executes quite possibly improvements cpu context and returns to the new job, nevertheless the stunning aspect comes in now, it executes 'CLREX' and therefore eradicating any exceptional lock held by earlier thread.
