Partially, yes.

#18328 is a workaround specific to the intermediate P2 versions.  An
equivalent patch is incorporated to release versions such as 9.3.6 as
CHANGE 2411:

2411.	[bug]		Allow using a larger number of sockets than FD_SETSIZE
			for select().  To enable this, set ISC_SOCKET_MAXSOCKETS
			at compilation time.  [RT #18433]

and CHANGE 2421 makes ISC_SOCKET_MAXSOCKETS even unnecessary knob:

2421.	[func]		Add new command line option '-S' for named to specify
			the max number of sockets. [RT #18493]
			Use caution: this option may not work for some
			operating systems without rebuilding named.

"Some operating system" actually means Solaris here.  CHANGE 2469
addresses this problem.

Note also that release versions on Solaris use /dev/poll instead of
select() by default, so none of these changes matter anyway.
