Low performance, big memory consumption; Writing 50KB/s, needs ~50MB of RAM.
captive-install-acquire should retry broken httpcaptive:// connections.
-Mount of the same device multiple times is allowed (no EBUSY kernel protection).
libcaptive/cc/ mmap(2)s whole SharedCacheMap; ext2fsd maps whole disk area!
STATUS_LOG_FILE_FULL should be handled everywhere; not just file_write().
User-specifiable proxy for captive-install-acquire (not just the GConf one).
