loader is aborted with 'out of memory'

[TAKAHASHI Yoshihiro]

I got the following error of the current loader if I put the xxx_after
line into loader.conf to wait a key after load the xxx module.

---
Error: out of memory
Module xxx
Error executing read -p "Press Enter"
Aborted!
---

The loader.conf is:
xxx_load="YES"
xxx_after="read -p \"Press Enter\""


Does anyone know what is wrong?
