This dynamic entry is added to lib.so.1 only. The OpenSolaris makefiles pass "-z rtldinfo=tls_rtldinfo" to the final link-edit of libc.so.1. ld.so.1 recognizes this dynamic tag, and calls the associated interfaces at process initialization. The Solaris process model, threads model, and ld.so.1 interaction with these models would be crippled without this handshake. -- Rod.
