Comment 15 for bug 455024

Googled up few related threads with solve mentioned adding swap. Even with 4G ram & 10G swap it didn't help me though for rather full 5.5T ext4 fs with big number of files. It seems that i could somewhat workaround it by specifying some middle fs size between one -M tried to reduce to and that of fs original size by calculating with bc #M_blocksize#*4/1024^2 and throwing few tenhs of gigs above that.
