While you're off in C the I/O manager and garbage collector are suspended.
Many C programs are not prepared to deal with the side effects of their
operation, such as being interrupted by timer signals; moreover, it is not
possible to have multiple handlers at the OS level for a signal, and C
programs may want to use the signal handlers themselves.
