It is managemed by malloc() of C library. When you free a block memory by free() function, it only return the memory to C library for later use, but C library not always return the memory to the kernel.
Since there is a virtual memory for modem OS, inactive memory will be paged to pager when more physical memory blocks are need. It don't hurt much if you have enough swap space. What you get from ps command is memory allocated by process, it don't means they are used by Python interpreter. - -- Thinker Li - [EMAIL PROTECTED] [EMAIL PROTECTED] http://heaven.branda.to/~thinker/GinGin_CGI.py -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.6 (FreeBSD) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iD8DBQFGATzJ1LDUVnWfY8gRAjSOAKC3uzoAWBow0VN77srjR5eBF0kXawCcCUYv 0RgdHNHqWMEn2Ap7zQuOFaQ= =/hWg -----END PGP SIGNATURE-----
