Yes, hmm, I tried it without success.
I did:
export LD_PRELOAD=/path/to/spd_readdir.so
strace -o ... /usr/bin/texlua /usr/bin/mtxrun --generate
(the bad command) and I still see stats and getdents out of
inode order.

I have now found the thread
Large directories and poor order correlation
from March 2011 on ext4-devel, interesting read.
Anyway, as far as I can see I cannot do much but
fsck -D
the filesystem and see if it gets better, right?
Best wishes

MARGATE (n.)
A margate is a particular kind of commissionaire who sees you every
day and is on cheerful Christian-name terms with you, then one day
refuses to let you in because you've forgotten your identify card.
