I did a dtrace on 2.19.47, using the default introductionary song that Lilypond
uses as a starting sample (when starting the Lilypond app)
#!/usr/sbin/dtrace -s
syscall::lseek:entry /execname == "lilypond"/ { printf("lseek for %s ",
execname); }
syscall::open*:entry /execname == "lilypond"/ { printf("%s %s", execname,
copyinstr(arg0)); }
Searching within the created log-file of all dtrace hits for "open", so that
only the open* entries are found shows that apparently the lseek-explosion
occurs while lilypond is scanning the Mac OS X Fonts (this was not the first
run of 2.19.47, so the initial font-scanning of the first run can not be blamed
(unless the changes from 2.19.46 to 2.19.47 broke the font-caching system for
Mac OS X of course)):
CC-ing lilypond-devel as this may provide useful information for them too
