more eating CPU

[Joakim Tjernlund]

We noticed a hung more command, consuming 100% CPU. strace
showed this:

write(1, "\r                               "..., 114) = -1 EIO (Input/output error)
read(3, "", 4096)                       = 0
write(1, "\r                               "..., 114) = -1 EIO (Input/output error)
read(3, "", 4096)                       = 0
write(1, "\r                               "..., 114) = -1 EIO (Input/output error)
read(3, "", 4096)                       = 0
write(1, "\r                               "..., 114) = -1 EIO (Input/output error)
read(3, "", 4096)                       = 0
write(1, "\r                               "..., 114) = -1 EIO (Input/output error)
read(3, "", 4096)                       = 0
write(1, "\r                               "..., 114) = -1 EIO (Input/output error)
read(3, "", 4096)                       = 0
write(1, "\r                               "..., 114) = -1 EIO (Input/output error)
read(3, "", 4096)                       = 0
write(1, "\r                               "..., 114) = -1 EIO (Input/output error)

This is on BusyBox v1.14.2, I know it is a bit old but I figured I report it anyway.
