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

"Even Better(tm)" would be if
ln /proc/<id>/fd/<nr> whatever
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

wants a "you asked for it, you got it" text editor -- complicated,
cryptic, powerful, unforgiving, dangerous.
