Thanks for reporting the above problem!
It seems to be a likely problem.

Unfortunately we are now in holiday periods in Japan (Golden Week
holidays).  So, I can't test it.
I'd like to look into the problem after the holidays, maybe on Wednesday
or Thursday.

Before that, could you tell me some information on your PC ?
e.g. NILFS version, kernel version, memory amount, and so on.

Cheers,
