Yes, you'd have to do the check every time. But one simple comparision
would seem to be insignificant compared to the time the actual dlopen()
would take to load the library. Not to mention the 4 calls to dlerror()
that we've already added to compensate for glibc. Even those alone
should greatly outweigh the time this check takes. And I'm working
under the assumption that dlopen() isn't a particularly time-critical
function. Does it work though?
