Yes, we use record over NFS for a large number of files (over 100
simultaneously) and for buffers of 20 milliseconds duration. To avoid too many
system call, context switching and so on we use this patch. 

Some comparisons :
[root at testg5 /tmp]$strace -f -v gst-launch audiotestsrc num-buffers=10000 !
filesink location=/tmp/t.dat buffer-size=10 2>&1 | grep write | wc -l
525
[root at testg5 /tmp]$strace -f -v gst-launch audiotestsrc num-buffers=10000 !
filesink location=/tmp/t.dat 2>&1 | grep write | wc -l
5023

For us reducing the number of writes reduces overhead on the nfs client and on
the nfs server. We also reduce side effect of context switch on the system.
