lilypond-book runs out of memory: large file compilatioin fails

[Nikita]

I have a tex document with large number of lilypond snipsets, say about several
thousands. When I run lilypond-book 2.10.25 on it I get the following error
while dissecting:

Dissecting...Traceback (most recent call last):
  File "/usr/bin/lilypond-book", line 1879, in <module>
    main ()
  File "/usr/bin/lilypond-book", line 1845, in main
    chunks = do_file (file)
  File "/usr/bin/lilypond-book", line 1723, in do_file
    chunks = find_toplevel_snippets (source, snippet_types)
  File "/usr/bin/lilypond-book", line 1355, in find_toplevel_snippets
    m = res[type].search (s[index:endex])
MemoryError

My OS is Ubuntu with 4G memory. When I see `top` during compilation I see that
the free memory is going down and in 5 minutes I get the error above. For small
files everything is going right.
