// c-ares resolver is known to be buggy.
//
// There is no way to configure it properly without a JVM on Android,
// because Android lacks traditional resolv.conf.
//
// For standalone Android programs, it is impossible
// to contact ConnectionManager outside the JVM; this breaks c-ares DNS resolution.
// As we can not distinguish builds of Android apps from standalone Android programs.
//
// During mapkit experiments, c-ares was adding about 10ms to each query timespan.
//
//
// On Linux it caches /etc/resolv.conf contents and does not invalidate it properly
