the reason it is saved is because of the APR interface for getting an
error string from a dso load error...  you don't pass in the
system-specific error value (e.g., errno on Unix) but instead you pass
in the apr DSO handle...  since strerror() is allowed to overlay the
buffer containing the error string, we don't simply save the
strerror() result but instead save the errno... as for why the APR
interface is designed that way: some platforms have additional
information available (beyond any sort of errno-like numeric value)...
