1.2.1.  Bog standard with only Aaron's pmap.c patch.

Ah.  Well, as I said, the result of "unlimit" was

netbsd4me:1:89 % unlimit
netbsd4me:1:90 % limit
cputime         unlimited
filesize        unlimited
datasize        65536 kbytes
stacksize       65536 kbytes
coredumpsize    unlimited
memoryuse       58544 kbytes
descriptors     956 
memorylocked    58544 kbytes
maxproc         276 

This is enough for 4.0beta2, but 4.0beta3 doesn't work.

Oh, btw, I ran 4.0beta3 on a SPARCstation 2 under SunOS 4.1.3 and it worked
fine; then again, that machine had 128 Mb of RAM and 192 Mb of swap ... but
this still smells like a NetBSD problem.  (Actually, the real problem is
Netscape releasing the ultimate bloatware of the Universe, but hey ... )

This looks like it is probably the problem.  MAXTSIZ (max text size) in 1.2.1
is set to 8 Mb; in -current it's 64 Mb:

netbsd4me:1:105 % diff -rc0 /usr/src/1.2.1/sys/arch/sparc/include/vmparam.h vmparam.h

And gee, guess what size Netscape 4.0beta3 is, versus 4.0beta2?

netbsd4me:1:106 % size /usr/local/bin/netscape-4.0beta*                         
text    data    bss     dec     	hex
8077312 1966080 188184  10231576	9c1f18 /usr/local/bin/netscape-4.0beta2
9355264 2359296 201048  11915608	b5d158 /usr/local/bin/netscape-4.0beta3

8077312 < 8388608 == 8 * 1024 * 1024; 9355264 ain't.

Thanks Mat!
