From a discussion with Petr Rockai: "the possibly non-intuitive bit
that you probably didn't notice is that the hashset is supposed to be
passed to each thread by value. The copy semantics of the entire
hashset are that of a shared pointer: multiple copies share the same
underlying data. Each thread *must* have its own private copy of the
hashset object (there are bits of state that each thread needs for
bookkeeping and those must not be shared)."

Swarming implies that a single instance of the kripke
structure (or product) will be explored by diffrent threads
with their own exploration order. Most of the modification
aims to have a thread safe kripke structure.

Passing atomic propositions by reference allows to
save very little memory so it doesn't worth complexifying
memory management.

From the working draft: "The macro ATOMIC_FLAG_INIT shall be defined
in such a way that it can be used to initialize an object of type
atomic_flag to the clear state. The macro can be used in the form:
atomic_flag guard = ATOMIC_FLAG_INIT; It is unspecified whether the
macro can be used in other initialization contexts."
