This isn't really appropriate to the maintainers list but I'll reply anyway.
While it's true that the native cyg_threads stuff is the most efficient,
you'll find that eCos is a sufficiently lightweight operating system
anyway that the very small overhead of using POSIX threads will not have
any real impact. If your requirements are that it is cross platform, then
POSIX threads are definitely the way to go.
