Summary:                    glibc 2.11.1 causes asterisk to not start due to
return code from dlclose
Description: 
On Fedora-12, with its current glibc (glibc-2.11.1-1), asterisk fails to
start up when it loads any module.

In main/loader.c there are 4 instances of the following code:
     while (!dlclose(lib));

dlclose() in glibc-2.11.1-1 returns 0 (SUCCESS) even if the library has
already been closed, and consequently the while loop never terminates.

On Fedora-11 (with glibc-2.10.2-1) and Fedora-13 (with glibc-2-11-90.14),
dlclose() returns -1 if the library is already closed, and so the problem
does not occur.

This issue certain occurs with asterisk version 1.6.1.12 and later
(including current SVN head).
