Yup.  Looks like you are right.  I just grabbed the libc6.1 deb for 
2.3.2.ds1-22, extracted the contents and dynamically linked the C threadtest 
against it (i.e., './LD_LIBRARY_PATH=. ./ld-2.3.2.so ~/tmp/threadtest' in the 
extracted lib directory) and the threads clean up just fine.

I checked the libc6.1 change logs for thread and alpha entries between the two 
versions and only found the following (the 2.3.5-3 changelog):
  * This version fixes some bugs that are marked as fixed-upstream:
    -Fix broken pthread_cleanup_push on Alpha.  (Closes: #197988)

The proc weirdness issue (not differentiating between threads and processes),  
still exists when using the earlier libraries.  I wonder if that is a 
pthreads issue or a kernel one?
