cat /proc/<id>/fd/<nr> > whatever
actually works.

"Even Better(tm)" would be if
ln /proc/<id>/fd/<nr> whatever
or
ln <Inode> whatever (lsof delivers the needed Inode-nr)
would work.

Otherwise you have a problem to recover files when you have insufficent
disc space. Imagine a file that is 1GB in size and you have 512MB left
on the hdd. Currently i don't see a chance to recover such a file
without problems.

Real Programmers consider "what you see is what you get" to be just as
bad a concept in Text Editors as it is in women. No, the Real Programmer
wants a "you asked for it, you got it" text editor -- complicated,
cryptic, powerful, unforgiving, dangerous.
