--- Comment #59 from Karl <karl at lrak.net> ---
This bug is a pain.. 

I found a way to recover using PV .. a work-around

1) find the process+fd by looking directly in /proc:

ls -al /proc/*/fd/* 2>/dev/null | grep {filename}

2) Then with pv thrown in:

tail -c +0 -f /proc/{procnum}/fd/{fdnum} | pv -s {expectedsize} >
{recovery_filename}

You may need to Ctrl-C when done (ls /proc/{procnum}/fd/{fdnum} will tell you
that the file no longer exists)), but if you know the exact size in bytes, you
can use pv -S to make it exit when the count is reached.
