Thank you, this is a nice workaround :) IO::Handle accepts this file handle because it thinks that it is opened for writing.

From the strace output it seems that this does in fact fsync the directory. Excerpt:

open("/etc/", O_RDONLY)                 = 3
dup(3)                                  = 4
fsync(4)                                = 0

I don't think the dup() hurts the functionality. Though of course I cannot be sure because I'd have to crash my system repeatedly to see if the effect is the same.
