Both of these issues are reliably unreliable, in that they happen every 1 out of 5 reboots or so.

As Kevin said, please file bugs. This isn't your fault.

Of course this won't work for services that are on-demand/inactive, but how about something like this (untested, written in Mail):

#include <mach/mach_time.h>
#include <servers/bootstrap.h>

char *servicename[] = {
    "com.apple.CoreServices.coreservicesd",
    "com.apple.windowserver.active"
};

bootstrap_status_t serviceactive;
mach_timebase_info_data_t info;
(void)mach_timebase_info(&info);
uint64_t poll_interval = 1000000000ULL * info.denom / info.numer; // 1 second
uint32_t i = 0;

do {
while (bootstrap_status(bootstrap_port, servicename[i], &serviceactive) == BOOTSTRAP_UNKNOWN_SERVICE && ! serviceactive) {
mach_wait_until(poll_interval + mach_absolute_time());
}
} while (++i < sizeof(servicename) / sizeof(servicename[0]));

Please, please file bugs. Thanks! :-)
