[R] logging interim results using foreach/doMC

I am converting a large process to a parallel backhend using doMC and
foreach. Basically, I havea long list of input graph files and each of
them calls soem basic igraph package functions. I am parallelizing the
run, in order to save time. All works fine, and each %dopar% call ends
with a vector of results that at the end got fed into a data frame and
saved as a csv table.
When I did this in serial, I was appending to the table as results came,
allowing for a continuous log in case the server would crash or get out
of memory or similar.
Using %dopar% I have no idea how I could rbind the results while running
Does anyone have an experience with logging results during a parallel run?
