Commen= t # 56 on bug 97879<= /a> from Grazvydas Ignotas 
Is the async I/O thread doing a lot of memory allocations?

If so, perhaps the malloc implementation is slowed down by having large amo=
unt
of small allocs/frees from shader compiles and/or fragmentation of it's free
space. I wonder if it's possible to put mesa on a separate allocator without
affecting the rest of the app.
If the game is 32bit, it could also be that the address space is almost ful=
ly
mapped and mmap is struggling to find holes to fit the new allocations in.

Just some random guesses there.
