core: Fix double checking
These getInstance() methods implement a double-checking scheme to
initialize the instance static member.
In order for this mechanism to operate correctly, the instance member
should be defined as volatile (see, e.g.,
http://www.cs.umd.edu/~pugh/java/memoryModel/DoubleCheckedLocking.html).
