So, Since liferea and Firefox both tend to be somewhat sluggish under high IO load, even when they shouldn't be doing much out of it, I figured I'd get it sorted.

And while doing so, I'd also toss in the fix for Adobe Flash that Linus Torvalds posted in the Fedora bugzilla (#638477) earlier.
#include <sys/types.h>

void *memcpy(void *dst, const void *src, size_t size)
{
void *orig = dst;
asm volatile("rep ; movsq"
:"=D" (dst), "=S" (src)
:"0" (dst), "1" (src), "c" (size >> 3)
:"memory");
asm volatile("rep ; movsb"
:"=D" (dst), "=S" (src)
:"0" (dst), "1" (src), "c" (size & 7)
:"memory");
return orig;
}

int fsync(int fd)
{
return 0;
}
int fdatasync(int fd)
{
return 0;
}

int msync(void *addr, size_t length, int flags)
{
return 0;
}

License? The sync parts are trivial and not licensable. The Linus part isn't much worse.
Remember, if it eats your data, you can pet it.
