  Somewhat technical: bit mask (must be 2^N-1) used against heap->st_count to
  determine the interval between string table resize checks.  A resize check
  is made when heap->st_count & DUK_USE_STRTAB_RESIZE_CHECK_MASK is zero.

  A large value makes string table grow/shrink checks less frequent.  Usually
  this has very little practical impact on memory performance.  There are
  corner cases, such as dereferencing a large number of strings simultaneously,
  where this parameter affects how many new strings need to be inserted before
  the string table shrinks to a more appropriate size.
