memory_watcher is a library that can be linked into chromium to trace the
memory allocations. It works by hooking the system allocation/deallocation
functions, and recording the actions.
To use memory_watcher in chromium:
(1) Compile the memory_watcher library (it is part of the solution by default)
(2) Run chromium with these flags "--memory-profile -no-sandbox"
(The instrumentation doesn't work with the sandbox)
(3) Hit ctrl-alt-D to generate a dump of the memory allocations.
This will create a log file called memorywatcher.logXXXX for every
chromium process (where XXXX is the pid).
The log file is a human readable text format, which can be further analyzed
using the helpers in the "scripts/" directory.
