+ <braunr> youpi: in ipc/ipc_hash.c, there is code which computes the size of
+ the global (space, port)->entry hash table
+ <braunr> youpi: you may be interested in tuning this one too
+ <youpi> I know
+ <braunr> ok
+ <youpi> the current value is not so bad
+ <youpi> it's big enough for buildds to run fine
+ <braunr> 256 if i'm right
+ <braunr> well
+ <braunr> it won't fail
+ <youpi> we're limited by the 4000 object limitation anyway
+ <braunr> since it's a chained hash table
+ <braunr> but increasing it may help performances a bit
+ <braunr> and it certainly can't hurt much
