welcome to Unix. this is how it is, and it's not just linux. and it's
not just glibc/linuxthreads. in your code do you go about setting all
signals to SA_RESTART? if not then you're subject to the vagaries of
whatever the default signal settings are.

ted mentioned ^Z... there's also strace/truss/ktrace (depending on your
flavour of unix). there's also page-out/in (and on some unixes there's
swap-out/in).

it's something which bites lots of folks. gnu tar had this bug for at
least 5 years, and may still have it -- i got tired of submitting the bug
fix.
