Hi,

TSRM is the thread-safe resource manager. you can find it at the TSRM CVS 
module which should be at php-src/TSRM at your checkout. 

TSRM is a mechanism to hold thread safeglobal variables in an threaded 
environment. See articles about extension writing or the releavant books for 
more.

A few pointers for material:
http://www.zend.com/php/internals/extension-writing1.php#Heading9
Schlossnagle, George: Advanced PHP Programming (ISBN:  0672325616)
Golemon, Sara: Extending and Embedding PHP (ISBN: 067232704X)

btw. LS means "local storage", not list.
