Seems reasonable.

In another case, when st_init_numtable() to initialize
local_storage fails, it might be left pointing the current
thread's local_storage, and cause double-free.  So I suspect
fib->saved_thread.local_storage should be cleared after
cont_init() in fiber_t_alloc().

Also, setting prev_fiber and next_fiber in root_fiber_alloc()
will be no longer needed.
