I have some questions about this syscall: One serious problem is that
the allocations seem to take a long time to complete (this is on ext3,
I've not tried ext4 on my host machine yet).  Is it possible to have
the fallocate happen 'in the background'?  Is the extent-based system
used by ext4 more efficient in this respect?

In the virt space, these:

 - libvirt storage backend
 - virt-install (python)
 - libguestfs / guestfish
 - ovirt (maybe?)

For the virt C code, it would be extremely useful to have the autoconf
state of play sorted out first, so we can just add the right macros to
our configure.ac scripts.
