I like this solution:

/* 3sync.c */
#include <unistd.h> /* for sync(2) */
#include <time.h>   /* for struct timespec and nanosleep(2) */

int main()
{
    struct timespec ts = { 0, 1000000L };
    sync();
    (void) nanosleep(&ts, 0);
    sync();
    (void) nanosleep(&ts, 0);
    sync();
    return 0;
}

Compiled and placed in $HOME/bin (which is in $PATH), and now it gets used quite frequently in other scripts I run. Which either (1) is horribly inefficient, and/or (2) shows how paranoid I am with data corruption. Sigh.
