Threads form a class of objects:
The current thread:
Thread-local variables:
Each thread has its own independent set of thread-local variables and newly-spawned threads begin with an empty set.
Global hashtable of all threads, keyed by id:
Threads have an identity independent of continuations. If a continuation is reified in one thread and then reflected in another thread, the code running in that continuation will observe a change in the value output by self.

Thread-local variables:
tnamespace ( -- assoc )
tget ( key -- value )
tset ( value key -- )
tchange ( ..a key quot: ( ..a value -- ..b newvalue ) -- ..b )
