BIND 9.16.1 on CentOS 6

[Anand Buddhdev]

Hi BIND developers,

The 9.16.1 release notes say:

"The system-provided POSIX Threads read-write lock implementation is now
used by default instead of the native BIND 9 implementation. Please be
aware that glibc versions 2.26 through 2.29 had a bug that could cause
BIND 9 to deadlock. A fix was released in glibc 2.30, and most current
Linux distributions have patched or updated glibc, with the notable
exception of Ubuntu 18.04 (Bionic) which is a work in progress. If you
are running on an affected operating system, compile BIND 9 with
--disable-pthread-rwlock until a fixed version of glibc is available."

CentOS 6 has an older glibc version, 2.12. Is it safe to compile BIND on
CentOS 6 with the system read-write lock implementation?

Regards,
Anand
