I said "...without killing". This included any signal.
And you are right, you have to know what you are doing (and being in

A sparse file is created if you do the "cat>" on all Unixes FS I know,
while another process is "appending"...
If you have a list of Unix/linux (excluding networked) file systems

If it happens twice, it's a feature.
If it happens more than twice, it's a design philosophy.
