A critical section of code is one in which data that may be
accessed by other threads are inconsistent. At a higher
level, a critical section can be viewed as a section of
code in which a guarantee you make to other threads about
the state of some data may not be true.
If other threads can access these data during a critical
section, your program may not behave correctly. This may
cause it to crash, lock up, produce incorrect results, or
do just about any other unpleasant thing you care to
imagine.
Other threads are generally denied access to inconsistent
data during a critical section (usually through use of
locks). If some of your critical sections are too long,
however, it may result in your code performing poorly
