Patches from Ben Mather.
...
Allow #f to leave (srfi 99) record constructors and predicates undefined.
Distinguish default immutable fields (raw identifier), from default
mutable fields (list of one identifier) in the syntactic layer by not
creating setters for the immutable fields. The record introspection
can still mutate such fields.
Fixes issue #190 .

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.

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.
