------------------ Additional Follow-up Comments ----------------------------
The -C option to ilrun can be used to alter the size of
a method cache page.  e.g. "ilrun -C 256 blah.exe" will set
the cache page to 256k rather than the default of 128k.

Summary:  Execution engine fails on large method size

Original Submission:  The pnet ee fails to execute with attached file. The same 
assembly executes correctly on the MS ee.

Err:

$ ilrun bruteforceadd2.exe
Test::DoSumLooping - method is too big to be converted (99610 bytes)
Uncaught exception: System.Security.VerificationException: Could not verify the 
code
        at Test.Main(String[])

Should provide the answer ... 

#define IL_CONFIG_CACHE_PAGE_SIZE               (128 * 1024)

ie 131k ... and this method is ~96k ?

A method requires an approximate 4x size of the IL code to decode (maybe even 
more needed for the unroller, this is simply for the CVM).

However whether we change in the "pnet/profiles/full" file
or this header file is left as an exercise to the reader :)
