Yes, even better if the burning software can get access to the device in
such a way that accesses from other processes result in "in use - go

O_EXCL When used with O_CREAT, if the file already exists
it is an error and the open will fail.
My man page doesn't mention anything about E_EXCL when used without
O_CREAT, but if the behaviour is return success only when the device
isn't in use (r or w elsewhere) and to prevent subsequent processes
from opening even read-only, then that looks like the solution. Does
the fact that growisofs/cdrecord don't seem to obtain exclusive access
to the device mean doing exactly that isn't actually possible, or
