This is correct. Note that I mentioned only the kernel....
BTW: the fact that the userland is from S5r3 was the main cause for calling
Solaris "Slowlaris" in it's early days. AT&T engineers did take their userland
sources and completely ignored all bugfixes and enhancements that did happen
between 1980 and 1990. dd(1) e.g. did not call valloc() but malloc(),
resulting in unneeded page faults, init.c did set SIGXCPU and SIGXFSZ to
SIG_IGN, causing resource limits to become rather unusable by default.
