It depends upon the stratum.  dummy_stratum and file_stratum (and
download_stratum?) will have no thread because nothing's running yet.

I should have earlier posted that a target has 0:N threads.

A non-threaded app having a single thread corresponding to the main process.

For the other strata, this should be (made to be) true.
A fallout from this change may be that the process_stratum and
thread_stratum can be merged.

It depends on what you mean by merge.

There would still be a thread layer that abstracted the POSIX user threads and below it a process layer that abstracted the more physical LWPs. However, the existing assumption that there was only one thread stratum and and only it could have threads would be removed.
