Looking at the man page, I think a better idea might be something like
this (untested):
VG = valgrind --log-fd=100 100>>valgrind.log [...]
I guess we will also need .NOTPARALLEL: too.
Alternatively, using the %p specifier so that at least there's a very
high chance that each instance will go to a separate file.
