You could try "strace": strace xterm -r bash -c exit
You'll probably see it either hang on a certain system call, or spin
through a small set over-and-over. Figuring out what the output
signifies is often hard (unless you see something obvious like a failing
open() call on a missing file).
Even more performance information, on an entire machine, can be
collected with "oprofile". It profiles all userspace software function
calls, and the kernel (if you want). However, since your CPU is 93%
idle, this kind of profiling might not help?
The rootkit is an interesting possibility.
