simple perl script bypasses limits
Any user with shell access, or with access to upload a cgi
script can exploit this to make machine thrash badly.
Seems to circumvent any limits in the kernel

[PATCH 00/13] x86/paravirt: Make pv ops code generation more closely match reality
This changes the pv ops code generation to more closely match reality.
For example, instead of:
callq *0xffffffff81e3a400 (pv_irq_ops.save_fl)
vmlinux will now show:
pushfq
pop %rax
nop
nop
nop
nop
nop
which is what the runtime version of the code will show in most cases.
This idea was suggested by Andy Lutomirski.
The benefits are:
- For the most common runtime cases

[PATCH 0/2] Change guestfs__*
libguestfs has used double and triple underscores in identifiers.
These aren't valid for global names in C++.
(http://stackoverflow.com/a/228797)
These large but completely mechanical patches change the illegal
identifiers to legal ones.
Rich.
