  What do you say? 1003520 bytes are returned to OS when @x goes out of

 because under linux Perl defaults to system malloc:
 % perl -V:usemymalloc
 usemymalloc='n';

This implies that on another OS, the system malloc() might be different? Right??

 if usemymalloc='y', then Perl uses Perl's malloc, in which case memory is
 not returned to the os.

Now, does this mean that if usemyalloc='y', memory is not returned to the OS, no matter
what the OS is, or is this OS dependent as well??
