Wow, I tried the recommendation of turning off the compressed folders
option (using link provided), and it fixed my problem!

I was surprised, as this problem had
a) just started happening, seemingly randomly, after 6 months of no
issue
b) there was no compressed file in the directory that was causing me
problems

Anyway - just saying "thanks" to the person who posted that - and
adding that it did seem to fix the problem for me...and I had the same
symptoms:

CPU 100%
process hang during file deletion
ntdll.dll!RtlIntegerToUnicodeString+0x67 identified by process explorer
as the thread causing the problem

Cheers,
-James
