No, it's not an incredibly bad idea.  You just need to make sure
that you handle the security issues.

Sure.  And someone could equally well replace /bin/ls or ~/.bash_profile
or (ms)corlib.dll with a program that does something completely different.
If the attacker has write access to your files, then you are already lost.

Obviously you need to make sure the cache is not world-writable...

That's OK, you can check that the program is verifiable
before compiling it down to machine code.
