Comment (by ryandesign):

 Replying to [ticket:59691 ryandesign]:
 > perhaps we are leaking file descriptors and at some point we just don't
 have any free descriptors left to use one to get the `xcodebuild`
 process's output.

 > the new i386 Snow Leopard worker [experiences] kernel panic when
 building perl modules sometimes

 Those kernel panics could also be caused by a lack of available file
 descriptors; see #60509.
