With a computer, you never need to remember! $ ls -l /proc/$pid/cwd is a symlink to the current working directory. Even if you change it with setwd() in R, it is still correct.

That is indeed what this is documented to do (and I mentioned in an
R-devel posting yesterday). Unfortunately it currently does not always
work: try it on a session running
try(repeat{1})
to see the problem.

Sending the process a SIGUSR1 signal: $ kill -USR1 pid will save the global environment in the file .RData, but you'll need to remember the current working directory of the process to find it.
