/* Implementation details
Dictionary contains one list that links all pairs, this way
order in which they were added is preserved. Each bucket has
its own list to hold all pairs in this bucket. Initially all
bucket lists are zeroed and we init them once we about to add
first pair.
When pair is removed it's unlinked from both lists; if it was
a last pair in a bucket list it stays empty in initialized state.
Preserving pair order is important for enumeration, so far testing
indicates that pairs are not reordered basing on hash value.
