Yeah, 4 of that 6 open calls look like this
5156 open("/usr/share/perl5/DateTime/Locale/yo.pm", O_RDONLY) = 4
5156 lseek(4, 0, SEEK_CUR) = 0
5156 fstat(4, {st_mode=S_IFREG|0644, st_size=11505, ...}) = 0
5156 read(4, "################################"..., 4096) = 4096
5156 lseek(4, 512, SEEK_SET) = 512
5156 lseek(4, 0, SEEK_CUR) = 512
5156 close(4)
My guess that's -T "/usr/share/perl5/DateTime/Locale/yo.pm"
One open call reads the file up to __END__ and the last one reads the
whole file.
So these multiple openings are a red herring, sorry.
