Hangs Reading Large Files

When an executable is performing a processor-intensive task without any
"hooks" for interrupts,  the "not responding"  status is normal, as is
the pinwheel -- which is doing what it's supposed to; it's just that
none of us like it when it spins for too long.

Subject: [R-SIG-Mac] R 3.2.2 Hangs Reading Files in El Capitan

Been a while, but wanted to close the page on a previous post describing
R hanging on readRDS() and load() for largish (say 500MB or larger)
files. Tried again with recent release (3.3.0).  Am able to read in
large files under El Cap.  While the file is reading in, I get a
disconcerting spinning pinwheel of death and a check under Force Quit
reports R is not responding.  But if I wait it out, it eventually reads
in.  Odd.  But I can live with it.

Thank for that. Makes sense.  Odd thing is I never noticed this behavior before El Cap.  In Mavericks, would see the small grey spinning progress indicator which was much more reassuring that things were as they should be.

Cheers
