Re: [9fans] plan 9 overcommits memory?

i can't remember whether anyone pointed this out as well (probably):
you'll need to ensure that each fork reserves as many physical pages as are 
currently
shared in the data space, for the life of the shared data,
so that every subsequent copy-on-write is guaranteed to succeed.
this will prevent some large processes from forking to exec much smaller images.
