Reset the current parameters in child threads.
...
This is simple and fast. Inheriting all threads causes immediate
problems with exception handlers, and in general should use
copy-on-write behavior so that child threads can't affect parents. If
we make an eager copy of the parameters we can filter out just the
exception handler, but then thread creation is expensive. The ideal
design might allow selectively enabling parameter inheritance.

The global ABI error object needs to be an immediate, since if

the ABI is incompatible we can't even necessarily refer to a
global from within the bad library.

Simplifying scheduler case where the only available thread is waiting on a port.
...
Instead of a one-time poll, we just use the default small sleep + loop case,
so we use the normal poll next time through the scheduler.
This fixes a potential case where a lone thread waiting on I/O could hang,
discovered by Lorenzo.

Another thread patch from Lorenzo. If we're reduced to scheduling
...
a single thread blocked on an fd and the poll fails, optimistically
unblock it (so it can block again naturally), instead of just running
it still in a wait status.
