+ * In hashmap the Path is a bit pattern that describes

+ * Since each hashmap node can only be up to 16 elements
+ * large we use 4 bits per level in the path.
+ *
+ * So a Path with value 0x110 will first get the 0:th
+ * slot in the head node, and then the 1:st slot in the
+ * resulting node and then finally the 1:st slot in the
+ * node beneath. If that slot is not a leaf, then the path
+ * continues down the 0:th slot until it finds a leaf.
+ *
+ * Once the leaf has been found, the return value is created
+ * by traversing the tree using the the stack that was built
+ * when searching for the first leaf to return.
+ *
+ * The index can become a bignum, which complicates the code
+ * a bit. However it should be very rare that this happens
+ * even on a 32bit system as you would need a tree of depth
+ * 7 or more.
+ *
+ * If the number of elements remaining in the map is greater
+ * than how many we want to return, we build a new Path, using

+ * These requirements are due to the 'filename' module
+ * in stdlib. This since it is documented that it
+ * should be able to operate on raw filenames as well
+ * as ordinary filenames.
+ *
+ * A raw filename *must* be a byte sequence where:
+ * 1. Codepoints 0-127 (7-bit ascii) *must* be encoded
+ * as a byte with the corresponding value. That is,
+ * the most significant bit in the byte encoding the
+ * codepoint is never set.
+ * 2. Codepoints greater than 127 *must* be encoded
+ * with the most significant bit set in *every* byte
+ * encoding it.
+ *
+ * Latin1 and UTF-8 meet these requirements while
+ * UTF-16 and UTF-32 don't.
+ *
+ * On Windows filenames are natively stored as malformed
+ * UTF-16LE (lonely surrogates may appear). A more correct
+ * description than UTF-16 would be an array of 16-bit
+ * words... In order to meet the requirements of the
+ * raw file format we convert the malformed UTF-16LE to
+ * malformed UTF-8 which meet the requirements.
+ *
+ * Note that these requirements are today only OTP
+ * internal (erts-stdlib internal) requirements that
+ * could be changed.
