Hm, that would be lots of pages taken up by *something*, then:

AlphaStation 200 4/233, 233MHz
8192 byte page size, 1 processor.
real mem = 16777216 (1294336 reserved for PROM, 15482880 used by NetBSD)
avail mem = 11616256
using 189 buffers containing 1548288 bytes of memory

Send instrumentation.  --:)

The strange thing is that I've done incredibly memory-piggy things
on this box already, notably making and running /usr/pkgsrc/games/lincity.
Eats lots and lots of memory, runs really slowly as a result, but doesn't
panic.

I have even done simultaneous makes of things, just for fun.

It could be that "make build" is just much bigger than that.

It does get quite large during the make cleandir in lib/libc...

Un(?)fortunately it didn't go kapow this time (for the first time).  
I have no idea why.
