Howto avoid a process beeing paged out?

[Clemens Eisserer]

Hi,

I run a time-critical application on a vServer which seems to have very
little memory (even 512mb are guaranteed).
Every page that hasn't been accessed the last few minutes is immediatly
swapped out, and if a request comes in the system is busy many seconds
loading the working-set of the application into memory again.

Is there any way to prevent applications from beeing swapped out?
I tried to call mlock(), but after this call dynamically loading shared
libraries failed :/

Thanks, Clemens
