I'd also suspect bugs in your code before bugs in perl (which do happen,
but are very rare, especially in something pretty core like file
operators).

Are you absolutely sure there are no other processes running something
on the filesystem that could somehow affect these files? As you've
already done a fair bit of investigation, it's likely to be something
quite strange, so don't rule anything out.
