IOW, it's a glibc feature :)

Stripping libpthread appears to be a very common mistake:

- we've seen it twice on this list in the last two weeks,
- I made it myself 4 weeks ago, even though I *knew* that libpthread
  must not be stripped.

I wonder if we should warn glibc users? Something like:

  Warning: your /lib64/libpthread.so.0 has been stripped.
  GDB will not see other threads, and multithreaded debugging will
  be unreliable.
  See http://sourceware.org/gdb/wiki/... for further info.
