And it seem you were right about that. After I increased the available
kernel memory from 128MB (default for a 1GB machine) to 256MB I could
rebuild the RAID without the machine getting stuck:

raid0: Reconstruction of disk at col 0 completed
raid0: Recon time was 7976.858062 seconds, accumulated XOR time was 0 us (0.000000)
raid0:  (start time 1180943157 sec 172287 usec, end time 1180951134 sec 30349 usec)
raid0: Total head-sep stall count was 0
raid0: 6678754 recon event waits, 4 recon delays
raid0: 3244449136 max exec ticks

The machine is still up and running.

	Kind regards
