Looks pretty good, except:
pthread_keys_max = strtol(pkm, (char **)NULL, 10);
Why cast NULL, why limit to decimal, this should be unsigned...?
Perhaps also limit it to a reasonable value.
No need to check for NULL before free.
pthread_keys_max = 0;
Why default to 0 on error? I would default to the current default.
long pthread_keys_max = 0;
Why initialize it, why long?
Traditionally we call the bail label out, err is confusing because
it is also a function name.
