 Writing large blocks of data to a JFFS file can fragment the heap. A
 recent performance change to untar has exposed this issue.

 The JFFS write creates a caches various nodes as it works. The code also
 allocates io vec buffers to hold data blocks greater than 256 bytes.

 A review does not seem to point to a leak but I am not 100% sure.
