Time limited scons team

Question

I want to limit the execution time of the program that I run on Linux. I put a line like in my scons script:

Command ("com", "," ulimit -t 1; myprogram ")

and tested it with a program with an infinite loop: it did not work, and the program was executed forever.

Did I miss something?
