I thought Windows already had a system message for something like that. Or at least it used to, although I can see why it would have been removed or at least deprecated. Unix could do it with a signal, but in general the application can't easily do that at times chosen by an external entity (consider that the act of finding such memory could inadvertently *increase* memory pressure on the system, since an application can't tell which of its pages aren't in core) The correct solution is to give the application the tools necessary for it to do its own memory management --- which is what the paper is about. - -- brandon s. allbery [linux,solaris,freebsd,perl] allbery@kf8nh.com system administrator [openafs,heimdal,too many hats] allbery@ece.cmu.edu electrical and computer engineering, carnegie mellon university KF8NH -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.10 (Darwin) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iEYEARECAAYFAky5yLEACgkQIn7hlCsL25UU/ACfXc8mmUeR2oIJMKGYSwd61JvM qC0AoJ7BrEf0+ApE+Ohr4BnyqfqBCQ4q =VBBc -----END PGP SIGNATURE-----
