I have these problems, too. My "work around" is to run stress program which eats megabytes of memory. Then I kill it and hope that there's big enough continuous chunk. It usually works.
Pavel PS: Perhaps kernel should do this itself? -- I'm really pavel@atrey.karlin.mff.cuni.cz. Pavel Look at http://atrey.karlin.mff.cuni.cz/~pavel/ ;-).
