For speed purposes, you may choose to ALSO keep a binary file with the
info.  AFTER confirming it is more recent in mtime than /etc/lddrv/wind,
you can save considerable time just picking it rather than re-scanning
the name list -- the kernel name list is vastly larger than it should be.

Alternatively, you can scratch the binary file on re-boots, and build it each
first-time it's used -- like most SAR implementations, if I recall correctly.
