That's true. I don't think it needs the zero entries, because all
the non-zero entries have index numbers.
My use case is:
Sun Ultrasparc 60
Solaris 2.6 native
target program with 945 sections (namely, gdb itself)
gdb built with SECT_OFF_MAX=1024, MAX_SECTIONS=1024
(gdb) break main
(gdb) maint print psymbols xx.psym
"maint print psymbols" takes 23 seconds to execute and produces a 7.1
megabyte output file. 74% of that output file is the zero entries in
section offset tables.
On a slower machine (400 MHz Intel PII) with bigger section tables (2048
lines), "maint print psymbols" takes so long to run that gdb.base/maint.exp
times out and fails.

You mean section table entries -- I'm not touching symbols at all.
