Comment(by strk):

 I verified that palloc, repalloc and pfree do _not_ give an interruption
 chance. But we could, in our wrappers, by explicitly calling the
 CHECK_FOR_INTERRUPTS macro.

 Effect of such macro on performance should be reviewed.

 Also, for GEOS to take advantage of interruptability we'd need to use the
 custom allocators from within GEOS itself.
